1. Preparation

Tools Required: Socket set, torque wrench, fluid catch pan, rags, UV light (if using dye).
Park the vehicle on a level surface and ensure the engine is off and cool.
Disconnect the battery to avoid any electrical issues while working on the steering system.

2. Remove the Steering Rack

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels for better access to the steering components.
3. Disconnect the steering column shaft from the steering rack.

5. Unbolt the steering rack from its mounting points and carefully remove it from the vehicle.

3. Inspect and Replace Seals or Rack

Sub-steps:
1. Inspect the steering rack seals for wear or damage. If damaged, replace the seals.
2. If the steering rack is extensively damaged or leaking from the housing, consider replacing the entire rack.
3. Clean the mounting surfaces and prepare for installation of the new or repaired component.

4. Install the New or Repaired Steering Rack

Sub-steps:
1. Position the new or repaired steering rack into the vehicle and secure it with bolts to the mounting points, tightening to the manufacturer’s torque specifications.
2. Reconnect the high-pressure and return hoses, ensuring they are properly tightened and free of leaks.
3. Reattach the steering column shaft to the steering rack.

5. Refill Power Steering Fluid

Sub-steps:
1. Refill the power steering fluid reservoir with the recommended fluid type, ensuring it is at the correct level.
2. Start the vehicle and turn the steering wheel from lock to lock to purge any air from the system.
3. Check for leaks around the steering rack and hoses during this process.
