Buyer's checklist
What to check before buying a used power steering pump
- Distinguish between traditional hydraulic belt-driven pumps and electro-hydraulic power steering (EHPS) units with integrated control modules.
- Spin the pulley shaft by hand to check for smooth bearing rotation, lateral shaft play, and inspect the front seal for fluid leaks.
- Verify high-pressure hose fitting connection style (o-ring flare vs banjo bolt) and return line nipple orientation.
- Check whether the pulley is press-fit or bolt-on, and confirm whether the unit includes the reservoir and fluid pressure sensor.
