Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, tie rod end puller, grease gun, and safety glasses.
Raise the vehicle using a jack and secure it with jack stands. Ensure the vehicle is on a flat surface.

2. Remove the Wheel

Loosen the lug nuts on the front wheel with a socket wrench.
Remove the lug nuts completely and take off the wheel to access the tie rod end.

3. Disconnect the Tie Rod End

Use a tie rod end puller to separate the tie rod end from the steering knuckle.
- Position the puller around the tie rod end and tighten until it pops free.
Remove the nut securing the tie rod end to the steering knuckle using a socket wrench.

4. Install the New Tie Rod End

Apply a small amount of grease to the threads of the new tie rod end.
Thread the new tie rod end into the steering rack by hand, then secure it with the nut, tightening to the manufacturer’s torque specification (typically around 37-45 ft-lbs).
Reconnect the tie rod end to the steering knuckle and secure with the nut, tightening it to the appropriate torque specification.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use the torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

6. Final Checks

Perform a visual inspection of the steering components to ensure everything is secure.
Check the alignment, and adjust if necessary.
