Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to avoid electrical issues during the repair.

2. Remove the Steering Rack

Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels for better access to the steering components.
Disconnect the high-pressure and low-pressure hoses from the steering rack using a wrench.
Remove the bolts securing the steering rack to the subframe using a socket set.
Carefully slide the steering rack out from its position.

3. Inspect and Repair

Inspect the steering rack for any cracks or obvious damage.
If the leak is from the seals, consider replacing the steering rack or seal kit.
For minor leaks, clean the area with brake cleaner and apply a suitable sealant as a temporary fix.

4. Install the Steering Rack

Position the new or repaired steering rack into place and secure it with bolts, tightening them to the manufacturer’s torque specifications (check service manual for specific torque values).
Reconnect the high-pressure and low-pressure hoses, ensuring they are tight and leak-free.
Reinstall the front wheels and lower the vehicle.

5. Refill Power Steering Fluid

Refill the power steering fluid reservoir with the recommended fluid type (typically ATF or specific power steering fluid – check owner’s manual).
Start the engine and turn the steering wheel from lock to lock to purge air from the system while checking for leaks.
