Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and turn off the engine.
Ensure the vehicle is secure with wheel chocks.
Disconnect the battery to avoid electrical issues.

2. Remove the Steering Rack

Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels to gain access to the steering components.
Detach the steering column shaft from the rack by removing the pinch bolt.
Disconnect the power steering lines from the steering rack, using a line wrench to avoid rounding the fittings.
Remove any retaining bolts that secure the steering rack to the subframe.
Carefully slide the steering rack out of the vehicle.

3. Inspect and Replace Seals

Disassemble the steering rack to access the internal seals.
Inspect all seals for wear or damage.
Replace any worn seals with OEM or high-quality aftermarket replacements.
Reassemble the steering rack, ensuring all components are properly aligned and securely fastened.

4. Reinstall the Steering Rack

Position the rebuilt steering rack back into the vehicle.
Secure it to the subframe using the original bolts, tightening to the manufacturer's specifications (typically between 30-50 ft-lbs).
Reconnect the power steering lines and ensure they are tight.
Reattach the steering column shaft and tighten the pinch bolt.

5. Refill and Bleed the System

Refill the power steering fluid reservoir with the manufacturer-recommended fluid.
Start the engine and turn the steering wheel from lock to lock several times to bleed any air from the system.
Check for leaks around the rack and connections. Add fluid as necessary.
