Solution

1. Preparation

Tools Required: Socket set, wrenches, power steering fluid, oil catch pan, rags.
Park the vehicle on a level surface and ensure it is securely on jack stands.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Remove the Steering Rack

Sub-steps:
1. Remove the front wheels for easier access to the steering components.
2. Detach the tie rods from the steering rack using a tie rod separator.
3. Disconnect the steering column shaft from the rack by removing the retaining bolt.
4. Unbolt the steering rack from its mounting points.
5. Remove the steering rack from the vehicle, noting the orientation and connections.

3. Inspect and Replace Seals

Sub-steps:
1. Clean the steering rack thoroughly to ensure no debris enters during disassembly.
2. Disassemble the steering rack housing to access the internal seals.
3. Inspect the internal components for wear or damage.
4. Replace any worn seals or O-rings with new ones, ensuring proper fit.
5. Reassemble the steering rack, applying appropriate torque to all bolts per manufacturer specifications.

4. Reinstall the Steering Rack

Sub-steps:
1. Position the steering rack back into place and secure it with the mounting bolts.
2. Reattach the steering column shaft and tighten the retaining bolt.
3. Install the tie rods back onto the steering rack and ensure they are torqued to specifications.
4. Connect the power steering lines, making sure they are secure and leak-free.

5. Refill and Bleed the Power Steering System

Sub-steps:
1. Refill the power steering fluid reservoir with the recommended fluid type.
2. Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
3. Check the fluid level again and add as necessary.
