Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical issues.

2. Remove the Steering Rack

Raise the front of the vehicle using jack stands for access.
Remove the front wheels using a socket set.
Disconnect the steering column from the steering rack by removing the pinch bolt and sliding the column off.
Disconnect the hydraulic lines from the steering rack using a wrench, and ensure to catch any fluid in a drain pan.
Remove the mounting bolts securing the steering rack to the subframe and carefully pull the rack out of its place.

3. Inspect and Replace Seals

Disassemble the steering rack according to the manufacturer’s service manual.
Inspect the inner and outer seals for wear or damage.
Replace any worn or damaged seals with new ones, ensuring they are properly seated.

4. Reinstall the Steering Rack

Position the repaired or replaced steering rack back into the vehicle.
Secure it with the mounting bolts, tightening to the manufacturer's specified torque (usually around 35-45 ft-lbs).
Reconnect the hydraulic lines and ensure all connections are tight to prevent future leaks.
Reattach the steering column, ensuring it is properly aligned and secured.

5. Fill and Bleed the Steering System

Refill the power steering fluid reservoir with the appropriate type of fluid (check the owner’s manual for specifications).
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid levels again and top off as necessary.
