Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Tie Rod Ends

Raise the Vehicle: Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove Front Wheels: Use a socket set to remove the lug nuts and take off the front wheels for better access.
Inspect Tie Rod Ends:
- Check for any signs of wear, such as play in the tie rod ends.
- If worn, proceed to replace.
Remove Old Tie Rod Ends:
- Use a wrench to disconnect the tie rod from the steering knuckle.
- Use a tie rod separator if necessary to free it.
Install New Tie Rod Ends:
- Screw the new tie rod end into the steering rack.
- Tighten to the manufacturer’s specified torque (typically around 45-50 ft-lbs, verify with the service manual).
Reattach Steering Knuckle: Connect the tie rod end back to the steering knuckle and tighten securely.

3. Inspect and Replace Steering Rack (if necessary)

Visual Inspection: If the tie rod ends are fine, check the steering rack for play or leakage.
Remove Steering Rack:
- Disconnect the steering column from the rack.
- Unbolt the rack from its mounts and remove any hoses attached.
Install New Steering Rack: Position the new steering rack and reverse the removal steps to install.
Reconnect Steering Column and Hoses: Ensure all connections are tight and secure.

4. Reassemble and Test
