Raise the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access the steering components.
Disconnect the steering linkage from the steering rack by removing the retaining bolt.
Carefully detach the power steering hoses from the rack, and be prepared for residual fluid spillage.
Unbolt the steering rack from its mounting points and remove it from the vehicle.

4. Inspect and Replace Seals

Inspect the seals on the steering rack for wear or damage.
If seals are damaged, replace them with new, OEM-spec seals.
Clean the area around the seals before reassembly to ensure a proper fit.

5. Reinstall the Steering Rack

Reinstall the steering rack by reversing the removal steps.
Ensure all bolts are torqued to the manufacturer's specifications.
Reconnect the power steering hoses and ensure they are securely fastened.

6. Refill the Power Steering Fluid

Fill the power steering reservoir with fresh, manufacturer-recommended power steering fluid.
Start the vehicle and turn the steering wheel from lock to lock to purge any air from the system.
Check the fluid level again and add more fluid if necessary.
