Solution

1. Preparation

Gather tools and parts needed for the repair.
Raise the front of the vehicle using a jack and secure it with jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Steering Rack

Tools Required: Socket set, torque wrench, fluid catch pan
Disconnect the power steering fluid lines from the steering rack using a wrench, allowing fluid to drain into a catch pan.
Remove the bolts securing the steering rack to the subframe using the socket set.
Carefully slide the steering rack out from the vehicle, being cautious not to damage any surrounding components.

3. Inspect and Repair

Inspect the steering rack for damaged seals or physical damage.
If the leak is from the seals, replace the steering rack seals or the entire steering rack if severely worn.
Parts Required: Steering rack seal kit or new steering rack (if necessary)

4. Reinstall the Steering Rack

Slide the new or repaired steering rack into position and secure it to the subframe with bolts. Torque the bolts to the manufacturer’s specifications (typically around 30-50 ft-lbs).
Reconnect the power steering fluid lines, ensuring they are tight to prevent future leaks.

5. Refill and Bleed Power Steering System

Refill the power steering fluid reservoir with the recommended fluid type (usually ATF or a specific power steering fluid).
Start the engine and turn the steering wheel from lock to lock several times to bleed any air from the system.
Check the fluid level again and top off if needed.
