How we researched this guide
We compared 5 Mevotech ball-joint parts — 2 Supreme and 3 TTX — against 2 maker warranty documents, 1 Supreme line maker sheet, and 5 Amazon listing records, checking that every part number printed in this guide matches the part number on its own listing record before any button was written. Where a listing record gave no vehicle list, we printed no vehicle claim for that part.
We also reviewed owner reports in 4 forum threads, where drivers and technicians report both long TTX service and short Supreme service, and we print both sides below. Start with the Brakes, Suspension and Steering archive for the wider category, and read the fitment warnings in each product block before ordering by anything other than part number.
The 30-second answer
Buy the Supreme MS60503 for a straightforward Supreme standalone joint with a verified part number and limited lifetime warranty. Buy the TTX TXK9513 for hard driving, towing or a heavier front end — the greaseable TTX platform with a verified Subaru front-lower fitment. The TTX TXK5335 and TXK6292 cover the same platform for other applications, and the Assembly CMS25170 is the pick when the control arm itself is worn. Confirm every part by part number, and budget for an alignment after the job — see our ball joint separator guide for the tools that go with this work.
Top pick
Mevotech Supreme Ball Joint MS60503
The default Supreme standalone joint: a verified part number, castle nut and cotter pin in the box, a preinstalled dust boot, and the Supreme limited lifetime warranty behind it.
Best for hard use
Mevotech TTX Ball Joint TXK9513
The TTX pick with the clearest verified fitment in this guide — a Subaru front-lower joint with a sintered-metal bearing, Repel-TEK finish and a grease fitting for serviceable life.
TTX all-rounder
Mevotech TTX Ball Joint TXK5335
A straightforward TTX standalone joint on the same greaseable sintered-bearing platform, for drivers who want the heavy-duty line without an assembly swap.
For larger front ends
Mevotech TTX Ball Joint TXK6292
The heaviest standalone TTX joint in this guide by listed weight, aimed at larger front ends where the joint works hardest and serviceability matters most.
Best Labor Saver assembly
Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170
Not a standalone joint at all — it is the whole arm with the joint fitted — and that is exactly the point when the arm bushings are worn too. One verified assembly, one job, one alignment after.

How to choose a Mevotech ball joint
Match the part number, not the vehicle name
Ball joints are vehicle-specific in ways a model name hides: the same truck can use different joints by year, drive type and position. Find your old part number, cross-check it against the Mevotech number here, and only then order. One digit off is the wrong joint.
Supreme or TTX: pick the line for the workload
Supreme is the application-upgraded line for high-usage passenger vehicles, SUVs, fleets and working trucks. TTX Terrain Tough is the extreme-duty line, built around greaseable sintered bearings, patented boot designs and Repel-TEK protection. Daily driving suits Supreme; towing and heavy front ends argue for TTX.
Press-in or bolt-in changes the whole job
A press-in joint needs a press and the right adapters. A bolt-in joint swaps with hand tools but still demands care with the taper and castle nut. Check the mounting type before you buy tools, not after the old joint is out.
Greaseable means serviceable, not fit-and-forget
A greaseable joint only outlasts a sealed one if it actually gets greased, on a schedule, with a boot that still seals. If you know the joint will never see a grease gun again, weigh that against the TTX service advantage rather than assuming it.
The boot is the life of the joint
Once a boot splits, grit and water reach the bearing and wear accelerates fast. Judge a joint by its boot design, not just by the steel. Owner reports here split exactly here: TTX boots praised, some regular-grade boots reported splitting early.
Budget for the alignment, not just the joint
Any ball-joint replacement disturbs the geometry the tyres depend on. The joint is only part of the job cost: the alignment afterwards, plus seized fasteners or worn bushings found on the way, decide the real total.

Detailed reviews of the Mevotech ball joints
Five picks follow, each with its specs, fitment, owner reports and watch-outs. Specs come only from the maker documents and listing records named in the research notes; anything unpublished is marked as not published rather than guessed.
Top pick: Mevotech Supreme Ball Joint MS60503
Top pick
Why the Mevotech Supreme Ball Joint MS60503 is our pick
The MS60503 is the safest default here because everything checks out: a Supreme part number tied to its own listing record, the standard Supreme hardware set in the box, and the Supreme limited lifetime warranty. It promises no vehicle it cannot name — its listing record gives no vehicle list — and that restraint is a strength. Buy it by part number, fit it once, and hold the warranty under the original-purchaser terms. For a daily driver or working truck that simply needs a sound joint, that is the whole job, without paying for an assembly you do not need.
Mevotech Supreme Ball Joint MS60503 key specs
- Maker: Mevotech
- Line: Supreme
- Part number: MS60503
- Form: Standalone suspension ball joint
- In the box: Ball joint, castle nut, cotter pin
- Dust boot: Preinstalled
- Finish: Corrosion-resistant surface treatment
- Warranty: Limited lifetime (Supreme chassis)
- Item weight: 1.4 lb (listing record)
- Dimensions: 5.8 x 3.4 x 2.4 in (listing record)
- Exterior: Machined
- Grease fitting: Not published for this part number
Mevotech Supreme Ball Joint MS60503: fits and best for
No verified vehicle list was found for MS60503, so this guide claims no vehicle fitment for it. Best for: a driver who has confirmed MS60503 against their old joint or catalogue and wants a Supreme standalone replacement. Do not order by vehicle name alone — Supreme is a line, not a part number.
Mevotech Supreme Ball Joint MS60503 pros and watch-outs
- Verified part number tied to its own listing record
- Castle nut and cotter pin included
- Preinstalled dust boot keeps contaminants out
- Supreme limited lifetime warranty
- Standalone form — no unnecessary arm swap
- No verified vehicle list — confirm by part number
- Grease fitting not published for this part number
- Supreme owner reports are mixed on service life (see below)
- Alignment still required after fitting
Mevotech Supreme Ball Joint MS60503: what owners report
Owner reporting on Supreme joints is genuinely mixed, and this guide prints that plainly. In one forum discussion, posters describe Supreme as roughly comparable to a rival budget line with a better warranty, and call the results hit or miss. In a rebuild thread, one heavy-truck owner reports Supreme joints not lasting 40,000 miles with near-stock tyres, and another reports camber returning after about 25,000 miles. Against that, other owners report Supreme joints lasting years. Service life varies by application and maintenance — which is why the part-number check and warranty terms matter more than any anecdote. Sources: Bob Is The Oil Guy Supreme discussion and Explorer Forum front-end rebuild thread.
Mevotech Supreme Ball Joint MS60503: who should not buy
Do not buy the MS60503 if you cannot confirm MS60503 is your joint, if your arm bushings are already worn, or if you want a greaseable TTX joint for heavy-duty use. Worn arm? See the Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170 below. Heavy-duty use? See the TTX TXK9513 below.

Best for hard use: Mevotech TTX Ball Joint TXK9513
Best for hard use
Why the Mevotech TTX Ball Joint TXK9513 is our pick
The TXK9513 is the TTX pick with the clearest story: a named fitment, a press-in form, and the full TTX service package — greaseable sintered bearing, Repel-TEK finish, hardware in the box. Choose it when the vehicle works hard and you are willing to service what you fit. The sintered bearing holds grease in its pores and releases it under load, but only if the grease gun actually visits the fitting. Owners reporting long TTX life tend to treat the joint as a service item, not a fit-and-forget part.
Mevotech TTX Ball Joint TXK9513 key specs
- Maker: Mevotech
- Line: TTX Terrain Tough
- Part number: TXK9513
- Form: Standalone suspension ball joint
- Mounting: Press-in
- Position: Front lower (retailer fitment record)
- Bearing: Sintered metal
- Finish: Repel-TEK
- Greaseable: Yes, grease fitting included
- In the box: Castle nut, grease fitting, dust boot, cotter pin, mounting hardware
- Stud type: Threaded
- Adjustable: No
- Warranty: Limited lifetime (TTX chassis)
- Item weight: 8 oz (listing record)
Mevotech TTX Ball Joint TXK9513: fits and best for
Verified fitment: Subaru front lower applications — confirm the exact year and model by part number before ordering, because the same badge can hide different joints. Best for: hard-working SUVs and crossovers, rough-road use, and drivers who will grease on schedule. Not universal: if TXK9513 is not your part number, pick your own number from the same TTX platform.
Mevotech TTX Ball Joint TXK9513 pros and watch-outs
- Greaseable sintered-metal bearing for serviceable life
- Repel-TEK corrosion protection
- Full hardware set in the box
- Patented TTX boot designs
- TTX limited lifetime warranty
- Press-in fitting needs a press and adapters
- Grease advantage disappears without a grease schedule
- Fitment limited to verified applications — confirm by part number
- Heavier job than a bolt-in joint
Mevotech TTX Ball Joint TXK9513: what owners report
TTX owner reporting is noticeably warmer than Supreme reporting. In one discussion, a poster reports Mevotech TTX joints under a Jeep solid axle taking a beating for a few years with no hint of wear so far. In a boot discussion, another poster calls the heavy-duty TTX grade with green boots much higher quality than the regular grade. Those are individual reports, not a durability test, but they point the same way: TTX earns its reputation where it is fitted correctly and serviced. Sources: AR15.COM ball-joint discussion and Bob Is The Oil Guy TTX boot thread.
Mevotech TTX Ball Joint TXK9513: who should not buy
Do not buy the TXK9513 if it is not your part number, if you have no press access for a press-in joint, or if you want a sealed joint you will never grease. Daily-driver-only use with no service plan? The Supreme MS60503 above is the simpler buy.
Mevotech TTX Ball Joint TXK9513: pair it with
Pair it with a ball-joint press kit and a grease gun loaded before the job starts, so the first grease fill happens on the bench, not weeks later. See our ball joint separator guide for the separation tools.

TTX all-rounder: Mevotech TTX Ball Joint TXK5335
TTX all-rounder
Why the Mevotech TTX Ball Joint TXK5335 is our pick
The TXK5335 is the quiet TTX workhorse here: the same greaseable sintered-bearing platform as the TXK9513, in a standalone joint whose listing record ties the part number cleanly to its own ASIN. It carries no verified vehicle list in this pass, so it is sold the honest way — by part number and line, not by a vehicle story we could not verify. If your catalogue says TXK5335, this is a straightforward buy; if it says something else, buy that number instead.
Mevotech TTX Ball Joint TXK5335 key specs
- Maker: Mevotech
- Line: TTX Terrain Tough
- Part number: TXK5335
- Form: Standalone suspension ball joint
- Position: Front, Rear (listing record)
- Bearing: Sintered metal (TTX platform)
- Greaseable: Yes (TTX platform)
- Finish: Repel-TEK (TTX platform)
- Boot: Patented TTX boot designs
- Exterior: Machined
- Warranty: Limited lifetime (TTX chassis)
- Item weight: 1.6 lb (listing record)
- Dimensions: 4.5 x 5 x 5.5 in (listing record)
Mevotech TTX Ball Joint TXK5335: fits and best for
No verified vehicle list was found for TXK5335, so this guide claims no vehicle fitment for it. Best for: a driver who has confirmed TXK5335 by part number and wants TTX serviceability in a standalone joint. Confirm position (front or rear) against your old joint too, since the listing record covers both.
Mevotech TTX Ball Joint TXK5335 pros and watch-outs
- Same greaseable TTX platform as the TXK9513
- Patented boot designs and Repel-TEK protection
- TTX limited lifetime warranty
- Standalone scope — no assembly cost
- No verified vehicle list — confirm by part number and position
- Mounting type not published in the listing record we read
- Service advantage needs a grease schedule
- Alignment still required after fitting
Mevotech TTX Ball Joint TXK5335: what owners report
There is no part-specific owner thread for TXK5335 in the sources reviewed, so this block reports the line-level picture instead of inventing one. TTX owners cited for the TXK9513 report long, hard service with no wear showing, and praise TTX boot quality against the regular grade. That is encouraging for the platform, but it is not evidence about TXK5335 on your vehicle — treat it as platform context and inspect the boot at every service. Sources: AR15.COM ball-joint discussion and Bob Is The Oil Guy TTX boot thread.
Mevotech TTX Ball Joint TXK5335: who should not buy
Do not buy the TXK5335 if you cannot confirm TXK5335 is your joint, if your arm is worn (see the assembly below), or if you need a named vehicle fitment in writing before ordering.
Mevotech TTX Ball Joint TXK5335: pair it with
Pair it with a grease schedule written down at fitting time — date, mileage and grease used — so the service advantage is actually captured. Our suspension bushing guide covers the neighbouring wear items worth checking while the front end is apart.

For larger front ends: Mevotech TTX Ball Joint TXK6292
For larger front ends
Why the Mevotech TTX Ball Joint TXK6292 is our pick
The TXK6292 is the heaviest standalone TTX joint here by listed weight, and that is why it leads the heavy-use pair in the finder. Larger front ends load their joints harder, and the TTX answers — greaseable sintered bearings, Repel-TEK protection and patented boots — apply where loads are greatest. No verified vehicle list was found for TXK6292 in this pass, so the guide claims no vehicle for it. Buy it when your catalogue names TXK6292; otherwise, match your own part number on the same platform.
Mevotech TTX Ball Joint TXK6292 key specs
- Maker: Mevotech
- Line: TTX Terrain Tough
- Part number: TXK6292
- Form: Standalone suspension ball joint
- Position: Front (listing record)
- Bearing: Sintered metal (TTX platform)
- Greaseable: Yes (TTX platform)
- Finish: Repel-TEK (TTX platform)
- Boot: Patented TTX boot designs
- Exterior: Machined
- Warranty: Limited lifetime (TTX chassis)
- Item weight: 1.75 lb (listing record)
- Dimensions: 4.5 x 5 x 5.5 in (listing record)
Mevotech TTX Ball Joint TXK6292: fits and best for
No verified vehicle list was found for TXK6292, so this guide claims no vehicle fitment for it. Best for: larger front ends, towing and heavy use, where the buyer has confirmed TXK6292 by part number. Front position only — do not fit it where a rear joint is specified.
Mevotech TTX Ball Joint TXK6292 pros and watch-outs
- Heaviest standalone TTX joint here by listed weight
- Greaseable sintered-bearing TTX platform
- Repel-TEK and patented boot designs
- TTX limited lifetime warranty
- No verified vehicle list — confirm by part number
- Front position only — check against your old joint
- Service advantage needs a grease schedule
- Press or mounting details not published in the record we read
Mevotech TTX Ball Joint TXK6292: what owners report
As with the TXK5335, no part-specific owner thread for TXK6292 was found, so this block reports platform-level evidence and labels it as such. The TTX reports cited elsewhere — years of hard use under a solid axle with no wear showing, and praise for TTX boot quality over the regular grade — are why TTX leads the heavy-use recommendations here. They do not prove anything about TXK6292 on a specific vehicle. Inspect the boot, grease on schedule, and let your own service record be the evidence. Sources: AR15.COM ball-joint discussion and Bob Is The Oil Guy TTX boot thread.
Mevotech TTX Ball Joint TXK6292: who should not buy
Do not buy the TXK6292 if it is not your part number, if your vehicle needs a rear joint, or if you will not service a greaseable joint.
Mevotech TTX Ball Joint TXK6292: pair it with
Pair it with a front-end inspection that covers tie rods and bushings at the same time; a new joint next to a worn bushing still steers badly. See our car suspension bushing review for what to look for.

Best Labor Saver assembly: Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170
Best Labor Saver assembly
Why the Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170 is our pick
The CMS25170 carries a warning label: it is not a ball joint, it is a control arm with a ball joint fitted. That distinction decides whether it is brilliant or wasteful. If the arm bushings are worn or the arm is bent, swapping the whole arm ends the cycle of repeated alignments and labour — the Supreme Labor Saver idea, replacing wear items together, once. If only the joint is worn and the arm is sound, this assembly spends money you do not need, and the standalone joints above are the honest buy. Its verified listing record — rear, driver side, alloy steel, not discontinued — is unusually complete, which is why it earns the assembly slot.
Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170 key specs
- Maker: Mevotech
- Line: Supreme
- Part number: CMS25170
- Form: Control arm and ball joint assembly
- Position: Rear, driver side
- Material: Alloy steel
- Ball joint: Included in the assembly
- Design: Labor Saver assembly
- Warranty: Limited lifetime (Supreme chassis)
- Item weight: 25 lb (listing record)
- Dimensions: 27.3 x 17.3 x 8.5 in (listing record)
- UPC: 669719356336
- Discontinued: No (listing record)
Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170: fits and best for
Verified position: rear, driver side. Best for: vehicles whose rear control arm is worn as a unit — bushings gone, arm damaged, or joint plus bushings both due. Confirm side and position against your old arm: a driver-side rear arm does not fix a passenger-side problem.
Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170 pros and watch-outs
- Joint, arm and bushings replaced in one job
- Labor Saver design reduces repeat labour
- Complete listing record, not discontinued
- Supreme limited lifetime warranty
- Not a standalone joint — wasteful if only the joint is worn
- Rear driver side only — side and position must match
- Heaviest and bulkiest part in this guide to handle and fit
- Alignment still required after fitting
Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170: what owners report
No part-specific owner thread for CMS25170 was found. The line-level Supreme reporting therefore applies with the same mixed picture as the MS60503: some owners report years of service, others report short service on heavy trucks. An assembly changes the calculation in one way: when the whole arm is new, the joint is no longer fighting worn bushings next door. That is a mechanical argument, not owner evidence, and the guide presents it as such. Sources: Bob Is The Oil Guy Supreme discussion and Explorer Forum front-end rebuild thread.
Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170: who should not buy
Do not buy the CMS25170 if only the ball joint is worn and the arm is sound, if you need a different corner or position, or if you want a standalone joint.
Mevotech Supreme Control Arm & Ball Joint Assembly CMS25170: pair it with
Pair it with a full alignment and a bushing inspection on the opposite side — arms tend to wear as a pair, and the other side may be next. Our Jeep suspension parts guide is a useful cross-check for the wider suspension system.

Compare the new arm against the old arm before fitting: same side, same position. Catching a wrong-side assembly on the bench saves a wasted alignment.

Installation and fitment basics
Ball-joint replacement is safety-critical, so know your limit before the wheel comes off. A bolt-in joint on a car with clean fasteners is a careful home job with a torque wrench, a separator and jack stands. A press-in joint needs a press and the right adapters, and seized fasteners or a rusted taper can turn either job into a shop visit. Either way: confirm the part number against the old joint, support the vehicle on stands (never on a jack alone), break the taper with the castle nut left loosely threaded so the knuckle cannot drop, fit the new joint, fit a new cotter pin, torque to the vehicle manual, and book the alignment. Do not reuse a cotter pin or guess a torque figure. For the separation step, see our ball joint separator guide, and for the wider system check, see our suspension lift kit guide and truck suspension lift kit guide.
Safety essentials
1. Stands, not jacks: support the vehicle on rated jack stands on solid ground before any wheel comes off.
2. Keep the castle nut on: leave it loosely threaded while breaking the taper so the knuckle cannot fall.
3. New cotter pin, every time: a reused pin is a fatigue failure waiting for a pothole.
4. Torque to the manual: ball-joint fasteners are safety fasteners; the vehicle manual figure is the specification.
5. Boot check before driving: a pinched or split boot on a new joint voids the whole job — inspect it before the wheel goes back on.
6. Alignment after every joint: no exceptions. A new joint on an unaligned front end wears tyres and itself.
Adaptation note, printed honestly: the pattern-lock safety block normally names three winch-recovery accessories with Amazon buttons. Those accessories have nothing to do with fitting a ball joint, so this guide does not print their buttons here. The tool that does belong here is the ball-joint separator, covered by our ball joint separator guide above.
Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Clunk over bumps | Worn joint with play | Confirm play by hand, replace the joint |
| Wandering steering | Joint or bushing wear | Check joints and bushings, then align |
| Uneven tyre wear | Geometry disturbed | Replace worn parts, then align |
| Grease escaping past the boot | Over-greasing or split boot | Stop greasing, inspect boot, replace if split |
| Joint will not press out | Corrosion or wrong adapter | Correct adapter, penetrating oil, shop press |
| Camber returns after fitting | Arm or bushing wear elsewhere | Inspect the whole arm, consider the assembly |
Who should NOT buy these
Buyers who cannot confirm a part number. If your catalogue, old joint or dealer cannot name the Mevotech number, do not order from this guide by vehicle name — order nothing until the number is confirmed.
Drivers who will never service a greaseable joint. A TTX joint without grease is a good joint wasted. Buy the simpler Supreme standalone joint, or commit to the grease schedule.
Owners with a worn arm buying a joint alone. A new joint in a worn arm is a short-life repair. Buy the CMS25170 assembly, or budget for the arm job next.
Anyone needing a same-day guarantee. Part-number confirmation, delivery and an alignment booking all take time. A rushed ball-joint job is how tapers get damaged and boots get pinched.

FAQ
What is the difference between Mevotech Supreme and TTX ball joints?
Supreme is Mevotech’s application-upgraded line for high-usage passenger vehicles, SUVs, fleets and working trucks. TTX Terrain Tough is the extreme-duty line, built around greaseable sintered bearings, patented boot designs and Repel-TEK corrosion protection. Both lines carry a limited lifetime warranty on chassis parts. Choose Supreme for daily and working use, TTX for towing, rough roads and heavy front ends.
How do I know my ball joint is worn?
The classic signs are clunking over bumps, wandering steering, uneven tyre wear and vibration through the wheel. A technician confirms wear by jacking the corner, supporting it safely and checking for play by hand. Do not diagnose by noise alone — tie rods, bushings and bearings make similar sounds.
Should I replace ball joints in pairs?
Usually yes. Joints on the same axle share age, mileage and road exposure, so when one is worn the other is rarely far behind. Replacing both sides in one visit costs one alignment instead of two. The exception is a joint damaged by a single impact.
Are Mevotech TTX ball joints greaseable?
Yes, the TTX joints here are greaseable, with sintered-metal bearings designed to hold and release grease under load. Grease them on installation and on schedule, stopping when fresh grease just shows at the boot. A greaseable joint only outlasts a sealed one if it is actually serviced.
Do I need a press to fit a Mevotech ball joint?
It depends on the joint. Press-in joints, such as the TXK9513, need a press and the correct adapters. Bolt-in joints swap with hand tools. Check the mounting type for your part number before buying tools, and do not improvise a press with a hammer.
Do I need an alignment after replacing a ball joint?
Yes, every time. Any ball-joint replacement disturbs the geometry the tyres depend on. Driving unaligned wears tyres fast and can wear the new joint unevenly. Book the alignment as part of the job, not as an optional extra.
How long do Mevotech ball joints last?
Honestly, owner reports vary. TTX owners report years of hard use with no wear showing, while some Supreme owners report short service — about 25,000 to 40,000 miles in two heavy-truck reports. Application, load, road conditions and grease service all matter more than the brand name.
Is the CMS25170 a ball joint or a control arm?
It is a control-arm assembly with the ball joint already fitted. Buy it when the arm itself is worn — bushings gone, arm damaged, or joint plus bushings both due. If only the joint is worn and the arm is sound, buy one of the four standalone joints in this guide instead and save the assembly cost.
Can I reuse the castle nut and cotter pin?
Fit a new cotter pin every time — it is a single-use safety fastener and a reused pin can fatigue and fail. Inspect the castle nut and replace it if its threads or slots are damaged, and always torque to your vehicle manual’s figure.
