Solution

1. Preparation

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

2. Remove the Steering Rack

Lift the vehicle using a jack and securely support it with jack stands.
Remove the front wheels for easier access to the steering components.
Disconnect the steering column from the steering rack by removing the retaining bolt and separating the joint.
Remove the power steering lines from the steering rack using a wrench; be cautious as fluid may leak.
Unbolt the steering rack from its mounting points using a socket set (torque specifications: refer to the service manual).
Carefully slide the steering rack out from the vehicle.

3. Inspect and Replace Seals

Clean the area around the steering rack to prevent contamination.
Inspect the inner and outer seals for damage or wear.
If seals are damaged, replace them with new ones. Use a seal puller for removal and apply a suitable lubricant to the new seals to ease installation.

4. Reinstall the Steering Rack

Position the steering rack back into place in reverse order of removal.
Tighten the mounting bolts to the specified torque values from the service manual.
Reconnect the power steering lines securely, ensuring no cross-threading occurs.
Reattach the steering column joint and tighten the retaining bolt.

5. Refill Power Steering Fluid

Refill the power steering reservoir with the correct type of fluid (refer to the owner's manual for specifications).
Bleed the steering system by turning the steering wheel from lock to lock several times with the engine off, then start the engine and repeat.
