How to choose professional power steering tools kits for cars
Hub diameter first
Pulley pullers are sized by hub diameter, and the kits in this guide cover hubs from 1-1/8 inch upward. Measure the hub before buying, and choose a kit whose range includes your hub with room on both sides, rather than a kit that only just fits.
Puller versus installer
A puller removes a pressed-on pulley, while an installer presses it back on squarely without damaging the pump shaft. A kit that does both is worth more than a puller alone, because an installer thread damaged on refitting can ruin a pump.
Pump families and fitment
Saginaw, Thompson and Ford C111 and C2 pumps use different pulley and shaft details, and a kit must list your pump family to be trusted. Check the maker fitment list for your exact vehicle and pump, not just for the make name.
Steel quality and thread care
Heat-treated steel and a clean, lubricated forcing screw resist bending and thread damage on a stubborn pulley. Keep threads clean, lubricate the forcing screw per maker guidance, and stop if the screw binds rather than forcing it.
Two-groove and alternator pulleys
Some kits also remove two-groove pulleys and alternator pulleys, which helps on a mixed fleet. Check whether the kit lists alternator work if you need it, rather than assuming every pulley kit covers it.
Case, storage and completeness
A blow-moulded case with labelled slots keeps small screws, collars and jaws together between jobs. A kit missing one screw on the day is useless, so check the full contents list against the case before the first use.

Detailed reviews: professional power steering tools kits for cars
Each block below follows the same order: why it is a pick, key specifications from the maker, fit, pros and watch-outs, what owners report, who should not buy it, and what to pair it with. Pressed-on pulleys cannot be removed with a generic puller without risking the pulley, the pump shaft or the installer thread. The kits below are made for that exact job, and the hub sizes matter more than the brand name.
Best Overall: OEMTOOLS 37031 Power Steering Pulley Puller and Installer Kit
Best Overall: Most domestic cars
Why the OEMTOOLS 37031 Power Steering Pulley Puller and Installer Kit is our pick
The OEMTOOLS 37031 leads this guide because it covers the hub range most domestic cars need, from 1-1/8 to 1-3/8 inch, and lists Saginaw, Thompson and Ford C111 and C2 pumps. That fitment breadth matters more than any single feature, because a pulley kit that does not list your pump cannot be trusted for the job. The kit removes and installs, so one box covers both halves of a pulley job, and the green case keeps the parts together between uses.
OEMTOOLS 37031 Power Steering Pulley Puller and Installer Kit key specs
- Pulley puller and installer
- Hubs 1-1/8 to 1-3/8 inch
- Steel pulley clamp and screws

OEMTOOLS 37031 Power Steering Pulley Puller and Installer Kit: fits and best for
This kit fits most domestic vehicles, including Ford, GM, Chrysler and VW, with Saginaw, Thompson and Ford C111 and C2 pumps. It is best for a home garage or workshop that works on several domestic makes and wants one kit for pulley removal and refitting.
OEMTOOLS 37031 Power Steering Pulley Puller and Installer Kit pros and watch-outs
- Wide hub range covers most domestic pulleys.

- Lists Saginaw, Thompson and Ford pump families.
- Case keeps screws and clamps together.
- Not a harmonic balancer kit for crank work.
- Needs hub measurement before buying.
- Heavier than a single-purpose puller.

Best Budget: Occasional home pulley work
Why the Orion Motor Tech SP0400 Power Steering Pulley Puller and Installer Set is our pick
The Orion Motor Tech SP0400 is the budget pick in this lineup, because it gives a complete 7-piece pulley puller and installer set in heat-treated 1045 steel for Ford, GM and Chrysler vehicles. Its maker describes a disconnect tool and a blow-moulded case in the set, which helps a home garage keep small parts together. For an occasional pulley job, that completeness at a budget position is more useful than a larger professional kit.

- Pulley puller and installer
- 7-piece set
- 1045 steel, heat treated

Best for GM Ford VW: DPTOOL H41701 Power Steering Pulley Puller and Installer Tool
Best for GM Ford VW: GM, Ford and VW pulley work
Why the DPTOOL H41701 Power Steering Pulley Puller and Installer Tool is our pick
The DPTOOL H41701 is the GM, Ford and VW pick in this lineup, because its maker lists those makes plus Chrysler, with Saginaw, Thompson and Ford C111 and C2 pumps, and with GM 3.1 V6 and Quad 4 engines named. Its AISI 1045 medium-carbon steel construction, heat treated per maker, suits repeated use, and the full set includes the pressure screw, flange, ring, bearing and collar parts needed for a square refit. For a mixed domestic fleet, that named fitment is reassuring.

Best Workshop Kit: Workshop harmonic and pulley work
Why the Orion Motor Tech 49-Piece Harmonic Balancer and Pulley Puller Kit is our pick
The Orion 49-piece kit is the workshop pick in this lineup, because it goes beyond a single pulley job to cover harmonic balancer pulling, steering wheel pulling and power steering pulley work in one set. Its maker describes a heavy-duty kit with a power steering pulley puller and installer included, which makes it the right choice for a workshop that faces crank, steering and pulley jobs in the same week. The larger size and weight are the trade-off for that breadth.

Editorial judgement, not test results: the comparison above ranks published specifications and owner-report themes, not measured performance. No product in this guide was bought by us for evaluation.
Installation and use basics
Disconnect the battery where the maker procedure requires it, relieve belt tension, and remove the belt from the pulley. Fit the puller jaws squarely on the pulley hub, turn the forcing screw evenly, and remove the pulley without prying. For refitting, use the installer screw and collar to press the pulley on squarely to the maker depth, then refit the belt, check alignment, and test steering at low speed before a road test.
Work through the maker instructions for the exact product you buy, and keep the work area clean and dry before you start. Useful background reading includes a related WinchInsider guide, another related guide, and a further related guide.
Before the main job, lay out every part, check it against the maker contents list, and confirm that the size, fitment and compatibility match your vehicle or equipment. A missing seal, screw or adapter found at this stage costs minutes, while the same discovery halfway through a job costs far more, especially if a vehicle is already partly dismantled. Take a photo of the original setup before removing anything, so reassembly has a reference even if the maker diagram is unclear.
Safety essentials
- Disconnect the battery where the maker procedure requires it.
- Relieve belt tension before removing a pulley.
- Keep hands clear of the belt and fan during work.
- Lubricate the forcing screw per maker guidance.
- Stop if a screw binds, rather than forcing it.
- Check pulley alignment and belt seating before a road test.

Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Pulley will not move | Wrong jaw fit or seized hub | Check jaw fit, lubricate, and retry evenly. |
| Forcing screw binds | Dirty or dry thread | Clean and lubricate the thread, then retry. |
| Pulley wobbles after refit | Not pressed on squarely | Remove and refit with the installer, squarely. |
| Jaws slip off | Hub size mismatch | Check hub diameter and jaw selection. |
| Installer thread damaged | Cross-threaded or forced | Stop, inspect, and replace the damaged part. |
| Belt squeals after refit | Misalignment | Check pulley depth and belt seating. |
Who should NOT buy these
If you do not know the hub diameter. A pulley kit bought on brand alone may not fit. Measure the hub first, then choose a kit whose range includes it.
If the pulley is already damaged. A puller cannot save a cracked pulley. Replace the pulley and inspect the pump shaft before refitting.
If you only need a single removal. A full kit may be more than a one-off job needs. A loaner tool from a parts store, where available, may suit a single job better.
If the pump itself is failing. A pulley tool does not fix a noisy or leaking pump. Diagnose the pump first, and replace it if the maker guidance says so.

It is a tool that removes a pressed-on pulley from a power steering pump shaft without prying or hammering. It uses jaws on the pulley hub and a forcing screw to pull the pulley straight off, so the pulley and shaft are not damaged.
Do I need an installer as well as a puller?
Yes, for refitting. An installer presses the pulley back on squarely to the correct depth, without damaging the pump shaft thread. A puller alone cannot refit a pulley safely.
What hub sizes do these kits cover?
The kits in this guide cover hubs from 1-1/8 inch upward, with some kits covering 1-1/4, 1-5/16 and 1-3/8 inch hubs. Check the exact range for the kit you choose against your measured hub diameter.
Will these kits work on my car?
They are made for most domestic vehicles, including Ford, GM, Chrysler and VW, with Saginaw, Thompson and Ford C111 and C2 pumps listed on several kits. Check the maker fitment list for your exact vehicle and pump before buying.
Can I use a generic puller instead?
A generic puller may not grip a pressed-on pulley hub correctly, and it can bend the pulley or damage the shaft. A pulley-specific kit is the safer choice for this exact job.
How do I avoid damaging the pump shaft?
Use the correct installer collar and screw, keep threads clean and lubricated, press the pulley on squarely, and stop if anything binds. Forcing a bound screw is how shafts and threads get damaged.
What if the pulley is seized?
Check jaw fit and thread lubrication first, then apply steady, even force. If it still will not move, inspect for corrosion or damage rather than forcing it, and consider professional help.
Do these kits work on alternator pulleys?
Some kits list alternator pulley work, including two-groove pulleys, while others are power-steering only. Check the maker description for the exact kit if alternator work is needed.
How should I store a pulley kit?
In its case, with all screws, collars and jaws in their slots, in a dry place. A missing screw on the day of a job makes the whole kit useless, so check completeness after every use.
