Solution

1. Preparation

Gather all necessary tools and parts.
Raise the front of the vehicle using a jack and secure with jack stands.
Remove the front wheels for better access to the tie rod ends.

2. Remove the Tie Rod Ends

Loosen the Nut: Use a socket set to loosen the nut securing the tie rod end to the steering knuckle.
Separate the Tie Rod End: Use a tie rod end puller or a hammer to gently tap the steering knuckle to release the tie rod end.
Unscrew the Tie Rod End: Count the number of turns as you unscrew the tie rod end from the inner tie rod to maintain alignment.

3. Install New Tie Rod Ends

Screw in the New Tie Rod End: Start screwing in the new tie rod end to the inner tie rod, matching the number of turns taken during removal.
Reattach to Steering Knuckle: Align the tie rod end with the steering knuckle and reinstall the securing nut. Tighten to the manufacturer's specified torque (usually around 38-45 ft-lbs, but verify in the service manual).
Inspect and Adjust: Ensure the rubber boot is properly seated and free of kinks.

4. Reassembly

Reinstall the front wheels and torque lug nuts to the specified value (typically 80-100 ft-lbs).
Lower the vehicle back to the ground.
