Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to ensure safety.

2. Remove Underbody Covers (if applicable)

Use a socket set to remove any underbody covers obstructing access to the steering rack.
Keep the screws and clips organized for reinstallation.

3. Inspect and Identify Leak Source

Clean the area around the steering rack with a degreaser to remove old fluid.
Once cleaned, check for new fluid accumulation to identify the exact leak location.

4. Replace Seals or Steering Rack

If seals are leaking:
- Remove the steering rack from the vehicle following manufacturer-specific procedures.
- Replace any damaged seals using appropriate tools such as seal pullers.
- Reinstall the steering rack and ensure all connections are tight.
If the steering rack is damaged:
- Remove the rack by disconnecting any hoses, electrical connections, and mounting bolts.
- Install a new or refurbished steering rack following reverse order of removal.
- Torque all bolts to manufacturer specifications.

5. Refill Power Steering Fluid

After reinstallation, refill the power steering reservoir with the recommended fluid type.
Bleed the power steering system by turning the steering wheel from lock to lock several times while the engine is running.

6. Reinstall Underbody Covers

Replace any underbody covers removed earlier using the same screws and clips.
