Power Steering Rack Seal Kit – OEM-Grade Replacement ️

Why you need it

This kit restores tight, leak-free steering. The seals keep hydraulic pressure inside the rack, preventing fluid loss, pump strain, and vague wheel feel. If your wheel feels heavy, the rack seeps oil, or you hear groans at parking speeds, fresh seals are the smart fix.

How it works

A matched set of O-rings, lip seals, and Teflon rings surrounds the pinion shaft, rack piston, and end caps. These parts lock in ATF/PS fluid under high pressure while allowing smooth shaft travel. Quality materials resist heat, abrasion, and chemicals for long service life .

If the seals fail

You’ll see wet boots, drops on the subframe, foamy fluid, and intermittent assist. Continued driving risks pump starvation, bearing wear, steering wander, and uneven tires. In severe cases, assist can fade suddenly—unsafe and costly ⚠️.

Fitment and install tips

Ideal when rebuilding a rack showing seepage or play. Clean all grooves, polish shafts, lube seals with the correct fluid, torque end caps evenly, then bleed the system and finish with a wheel alignment ✅.
