Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, ball joint separator, tie rod end puller, grease, and cleaning cloths.
Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels using a lug wrench.

2. Remove Old Tie Rod Ends

Step 1: Locate the tie rod ends connected to the steering knuckle.
Step 2: Use the ball joint separator to disconnect the tie rod end from the steering knuckle by placing the separator between the knuckle and the tie rod end and striking with a hammer if necessary.
Step 3: Loosen the locking nut on the tie rod end using a socket.
Step 4: Unscrew the tie rod end from the inner tie rod. Count the number of turns to ensure proper installation of the new part.

3. Install New Tie Rod Ends

Step 1: Apply grease to the threads of the new tie rod end.
Step 2: Thread the new tie rod end onto the inner tie rod, using the same number of turns counted during removal to maintain alignment.
Step 3: Tighten the locking nut securely with a socket.
Step 4: Reconnect the tie rod end to the steering knuckle using the ball joint separator.

4. Reassemble and Lower Vehicle

Step 1: Reinstall the front wheels and tighten the lug nuts in a crisscross pattern.
Step 2: Lower the vehicle from the jack stands using the jack.
Step 3: Torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

5. Alignment Check

After replacing both tie rod ends, have a professional alignment performed to ensure proper steering geometry.
