Solution

1. Preparation

Gather tools: socket set, torque wrench, ball joint separator, and safety glasses.
Park the vehicle on a level surface, engage the parking brake, and lift the front of the vehicle using a jack. Secure it with jack stands.

2. Remove the Old Tie Rod Ends

Access the Tie Rod Ends
- Remove the front wheel to gain better access.
- If necessary, remove any splash shields or covers obstructing access to the tie rod ends.
Disconnect the Tie Rod End
- Use the ball joint separator to disconnect the tie rod end from the steering knuckle. Be careful to avoid damaging surrounding components.
- Unthread the tie rod end from the inner tie rod, counting the number of turns to ensure proper adjustment during installation.

3. Install New Tie Rod Ends

Prepare New Tie Rod Ends
- Apply anti-seize lubricant to the threads of the new tie rod ends if necessary.
Thread New Tie Rod End
- Screw the new outer tie rod end onto the inner tie rod, using the same number of turns counted earlier to maintain alignment.
Reconnect to Steering Knuckle
- Insert the tie rod end into the steering knuckle and secure it with the nut. Torque the nut to the manufacturer's specifications (typically around 30-40 ft-lbs, but check your service manual).

4. Alignment

After replacing the tie rod ends, it is crucial to have the vehicle's alignment checked and adjusted by a professional to ensure proper handling and tire wear.
