Reconnect the hoses and tighten the fittings.

5. Inspect and Repair Steering Rack

If leaks are found in the steering rack, remove the mounting bolts and detach it from the vehicle.
Replace any damaged seals or, if necessary, the entire steering rack.
Reinstall the steering rack and torque to manufacturer specifications.
