Most Likely Causes
- 1
Leaking pressure hose
High-pressure hoses can seep at crimps or crack.
- 2
Leaking return hose or clamp
Low-pressure return lines can harden or loosen.
- 3
Rack and pinion seal leak
Steering rack seals can leak into boots or drip from the rack.
- 4
Pump seal leak
The pump shaft or reservoir seal can leak and sling fluid.
How to Diagnose It
- 1
Check reservoir level
Low power steering fluid supports an active leak and can make the pump whine.
Tool: Owner manual, clean rag
- 2
Inspect hoses, pump, and rack boots
Wet boots can hide rack leaks. Look for fluid trail direction.
Tool: Flashlight
- 3
Differentiate from transmission fluid
Some systems use ATF; location and reservoir level help identify source.
Tool: Flashlight
How to Fix It
Replace leaking hose or clamp
Use power-steering-rated hose and correct clamps/fittings.
Repair pump or rack leak
Replace the failed pump or rack component after leak source is confirmed.
Bleed system after repair
Bleed air according to procedure to prevent noise and foaming.
Mistakes to Avoid
- Do not run the pump dry.
- Do not mix fluid types unless approved.
- Do not ignore heavy steering or whining after fluid loss.
