Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Steering Rack

Drain Power Steering Fluid:
- Place a drain pan under the power steering fluid reservoir.
- Remove the drain plug (if equipped) or disconnect the return hose to drain the fluid.
Disconnect Hoses:
- Use a wrench to disconnect the high-pressure and low-pressure hoses from the steering rack. Be prepared for minor fluid spillage.
- Plug the hoses with clean rags to prevent contamination.
Remove Steering Column Connection:
- Remove the retaining bolt securing the steering column to the steering rack using a socket wrench.
- Carefully disconnect the steering column from the rack.
Unbolt Steering Rack:
- Remove the bolts securing the steering rack to the subframe using a socket set.
- Carefully slide the steering rack out of its mounting position.

3. Inspect and Repair

Inspect Steering Rack:
- Check for cracks or severe wear on the steering rack housing.
- If the leak is from a seal, consider replacing the steering rack as a whole unit for reliability.
Replace Seals (if applicable):
- If only the seals are damaged, use a seal kit to replace them according to the manufacturer's instructions.

4. Install New or Repaired Steering Rack

Position Steering Rack:
- Slide the new or repaired steering rack into position, aligning it with the mounting points.
Bolt Down Steering Rack:
- Secure the steering rack with the bolts previously removed, tightening them to the manufacturer’s specified torque value.
Reconnect Steering Column:
- Reattach the steering column to the steering rack, securing it with the retaining bolt.
Reconnect Hoses:
- Reconnect the high-pressure and low-pressure hoses to the steering rack, ensuring they are tight and leak-free.

5. Refill Power Steering Fluid

Refill the power steering fluid reservoir with the recommended fluid type, following the manufacturer’s specifications.

6. Bleed the Power Steering System

Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check for leaks around the steering rack and hoses.
