Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the front of the vehicle using a jack and secure it with jack stands.

2. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheel to gain access to the tie rod ends.

3. Disconnect the Tie Rod Ends

Locate the tie rod ends at the steering knuckle.
Use a socket set to remove the nut securing the tie rod end to the steering knuckle.
If necessary, use a tie rod end puller to separate the tie rod end from the steering knuckle.

4. Inspect and Replace

Check the condition of the tie rod ends. If they are worn or damaged, proceed to replace them.
Install the new tie rod end by reversing the removal process. Ensure it is securely attached to the steering knuckle.
Torque the nut to the manufacturer's specifications (typically around 30-50 Nm).

5. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then use the torque wrench to tighten the lug nuts to the specified torque (usually around 100-120 Nm).

6. Alignment Check

After replacing the tie rod ends, have a professional alignment performed to ensure proper steering and tire wear.
