Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

Detach the power steering lines using the 13mm wrench, capturing any fluid in a container.
Unbolt the steering rack from its mounting points and carefully remove it from the vehicle.

3. Inspect and Repair

Inspect the steering rack for damage or cracks. If leaks are found, determine if the rack can be repaired or needs replacement.
If replacing, install a new steering rack, ensuring all mounting points align properly.
Reattach power steering lines and ensure they are tightened to manufacturer torque specifications.

4. Reassembly

Reinstall the steering column and secure it with retaining bolts.
Reattach any brackets or covers that were removed.
Reconnect the battery.
