Symptoms
Wet rack boots, a falling power-steering reservoir, and creaking or whining on every turn of the wheel.
The fix, step by step
- First confirm the source: clean the engine bay and recheck, because hoses and the pump can drip onto the rack.
- Then disconnect the tie-rod ends and pressure lines, unbolt the rack and swap in an OEM reman unit with new bushings.
- While it's out, remove and clean the reservoir and its mesh screen, and consider an inline filter.
- Bleed the system, then get an alignment.
