Disconnect the negative battery terminal to ensure safety while working on the steering system.

2. Remove Steering Rack

Tools Required: Socket set, torque wrench, wrench set, steering rack removal tool.
Lift the vehicle and secure it on jack stands.
Remove the front wheels for better access to the steering components.
Disconnect the tie rods from the steering rack using appropriate wrenches. Mark their position for alignment during reinstallation.
Detach any electrical connectors from the steering rack if equipped with electric power steering.
Remove the mounting bolts securing the steering rack to the subframe. Keep track of all hardware.
Carefully slide the steering rack out from its mounting position. Be cautious of any remaining fluid.

3. Inspect and Replace

Inspect the old steering rack for any cracks or damage.
If necessary, replace the steering rack with a new or reconditioned unit.
Lubricate the new rack's mounting points and reattach it to the subframe using the original bolts. Torque to manufacturer's specifications.

4. Reconnect Tie Rods and Components

Reattach the tie rods to the new steering rack, ensuring they are aligned as marked earlier. Torque to manufacturer's specifications.
Reconnect any electrical connectors, ensuring they are secure.
Reinstall the front wheels and lower the vehicle back to the ground.

5. Refill Steering Fluid

Fill the power steering reservoir with the appropriate type of steering fluid as specified in the owner's manual.
Start the engine and turn the steering wheel from lock to lock to bleed air out of the system. Check for leaks during this process.
