Disconnect the steering shaft:
- Unbolt the steering shaft from the steering rack using a Torx or hex wrench.
- Gently pull the steering shaft away from the rack.
Extract the steering rack:
- Carefully remove the steering rack from its mounting location.

3. Inspect and Clean

Inspect the rack:
- Examine the steering rack for damage, especially around the seals and bellows.

Clean the surrounding area:
- Use a degreaser to clean any residual fluid from the steering rack area and hoses.

4. Replace Seals or Rack

If replacing seals:
- Remove the old seals and install new ones according to the manufacturer’s specifications.
If replacing the entire rack:
- Install the new steering rack into the mounting position, reversing the removal steps.
- Torque the mounting bolts to the manufacturer's specifications.

5. Reconnect Components

Reconnect the steering shaft:
- Align and secure the steering shaft to the new or repaired rack.
Reconnect fluid lines:
