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 battery to avoid any electrical issues during repair.

2. Remove Power Steering Fluid

Using a siphon pump, remove the existing power steering fluid from the reservoir.
Dispose of the fluid according to local regulations.

3. Remove Steering Rack

Lift the vehicle securely using jack stands.
Remove the front wheels to access the steering components.
Disconnect the steering shaft from the steering rack using a socket set.
Detach the power steering hoses from the steering rack, using a wrench to prevent damage.
Unbolt the steering rack from its mounting points and carefully remove it from the vehicle.

4. Inspect and Replace Seals

Inspect the seals and boots of the steering rack for damage.
If leaks are detected, replace the worn seals with new ones (use OEM parts for best results).
Clean the steering rack thoroughly to remove any residual fluid.

5. Reinstall Steering Rack

Position the repaired or replaced steering rack back into its mounting location.
Secure the steering rack with bolts, tightening to manufacturer torque specifications (typically 30-40 ft-lbs).
Reattach the power steering hoses and ensure they are securely tightened.
Reconnect the steering shaft to the rack.

6. Refill Power Steering Fluid

Refill the power steering fluid reservoir with the recommended fluid type (typically CHF 202 or similar).
Start the engine and turn the steering wheel from lock to lock to purge any air from the system.

7. Final Checks

Inspect for any leaks around the steering rack and hoses.
Replace wheels and lower the vehicle from jack stands.
