Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Make sure the engine is off and the keys are removed from the ignition.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove the Tie Rod Ends

Tools Required: Socket set, wrenches, tie rod end puller (or hammer).
Loosen and remove the nut securing the tie rod end to the steering knuckle using the appropriate socket.
Use a tie rod end puller or gently tap the steering knuckle with a hammer to dislodge the tie rod end from the knuckle.
Remove the tie rod end from the steering rack by loosening the retaining nut and unscrewing it from the rack.

4. Install New Tie Rod Ends

Apply anti-seize compound to the threads of the new tie rod ends.
Connect the new tie rod end to the steering rack and tighten the retaining nut to the manufacturer's specified torque (typically around 30-40 Nm).
Insert the tie rod end into the steering knuckle and secure it with the nut, again tightening to the manufacturer's specifications (usually around 30-40 Nm).

5. Alignment Check

After installation, ensure that the vehicle is aligned properly. A professional wheel alignment is recommended.
