Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Jack up the front of the vehicle and secure with jack stands.

2. Remove the Tie Rod End

Loosen the Nut: Use a socket wrench to loosen the nut securing the tie rod end to the steering knuckle. Do not remove it completely yet.
Separate the Tie Rod End: Strike the steering knuckle near the tie rod end with a hammer to free it without damaging the threads. Once loose, remove the nut completely.
Disconnect the Tie Rod End: Pull the tie rod end out of the steering knuckle and remove it from the vehicle.

3. Inspect and Replace

Inspect the Old Tie Rod End: Check for play and wear. If worn, proceed with replacement.
Install New Tie Rod End: Align the new tie rod end in the steering knuckle and insert it. Hand-tighten the nut and then torque it to the manufacturer’s specifications (typically around 50-60 ft-lbs).
Adjust the Length: If necessary, adjust the new tie rod end to match the length of the old one to maintain alignment.

4. Reassemble and Lower the Vehicle

Reconnect Components: Ensure all components are reconnected correctly.
Lower the Vehicle: Remove jack stands and lower the vehicle back to the ground.

5. Alignment Check

After replacing, perform a wheel alignment to ensure proper handling and tire wear.
