Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Steering Rack

a. Lift the Vehicle: Use a jack to lift the front of the vehicle and secure it on jack stands.
b. Remove Wheels: Take off the front wheels to access the steering components.
c. Detach Tie Rods: Use a tie rod separator to disconnect the tie rods from the steering rack.
d. Disconnect Power Steering Lines: Use a wrench to disconnect the fluid lines from the steering rack. Be prepared for fluid spillage and have rags available.
e. Unbolt Steering Rack: Remove the mounting bolts securing the steering rack to the subframe using a socket set.

3. Inspect and Replace Seals

a. Disassemble the Rack: Carefully remove the ends of the steering rack to access the internal seals.
b. Replace Seals: Replace any worn or damaged seals and O-rings with new ones, ensuring proper orientation.
c. Clean Components: Thoroughly clean the steering rack components with a degreaser to remove old fluid and debris.

4. Reassemble and Install

a. Reinsert Rack: Position the steering rack back into the subframe and secure it with mounting bolts. Torque the bolts to the manufacturer's specifications (typically around 40-50 lb-ft).
b. Reconnect Power Steering Lines: Reattach the fluid lines to the steering rack and tighten securely.
c. Reinstall Tie Rods: Connect the tie rods back to the steering rack, ensuring they are properly torqued.
d. Reinstall Wheels: Put the wheels back on and tighten the lug nuts in a crisscross pattern.

5. Refill Power Steering Fluid

a. Add Fluid: Refill the power steering fluid reservoir with the appropriate type of fluid recommended by the manufacturer (usually ATF or specific power steering fluid).
b. Bleed the System: Start the engine and turn the steering wheel from lock to lock several times to purge any air from the system.
