Tools Required: Socket set, wrench set, power steering fluid catch pan, jack stands.
Raise the vehicle using a jack and securely support it with jack stands.
Drain the power steering fluid into a catch pan by removing the reservoir cap and hoses.
Disconnect the steering linkage from the rack using the appropriate socket/wrench.
Remove any brackets or bolts securing the steering rack to the vehicle frame.
Carefully slide the steering rack out from its mounting position, taking care not to damage adjacent components.

3. Inspect and Replace Seals

Tools Required: Seal puller, clean rags, torque wrench.
Inspect the steering rack seals for wear or damage.
If seals are damaged, remove them using a seal puller.
Clean the sealing surfaces on the steering rack.
Install new seals, ensuring they are seated properly.

4. Reinstall the Steering Rack

Slide the steering rack back into position, aligning it with the mounting holes.
Reattach any brackets and secure them with bolts, tightening to specified torque values.
Reconnect the steering linkage to the rack.

5. Refill Power Steering Fluid

Reconnect the power steering hoses to the reservoir and rack.
Fill the power steering reservoir with the recommended fluid type.
Start the engine and turn the steering wheel from lock to lock to purge air from the system.

6. Check for Leaks
