3. Install the new seals and apply a lubricant if required.

5. Reinstall Steering Rack

Sub-steps:
1. Position the steering rack back into place and bolt it securely to the mounting points with the specified torque settings.
2. Reconnect the steering shaft ensuring the bolts are tightened to specifications.
3. Reinstall any components that were removed during the process (e.g., front wheels).

6. Refill Power Steering Fluid

Sub-steps:
1. Fill the power steering reservoir with the recommended fluid type as per the owner's manual.
