Solution

1. Preparation

Gather all necessary tools and parts before starting the repair process.
Tools Required: Jack and jack stands, socket set, wrench set, torque wrench, steering wheel puller (if necessary).
Safety Warnings: Ensure the vehicle is on a flat surface, engage parking brake, and wear safety goggles.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Securely position jack stands under the vehicle to ensure it does not fall.

3. Remove the Wheel

Using a socket set, remove the lug nuts from the front wheel.
Take off the wheel and set it aside.

4. Remove the Tie Rod End

Locate the tie rod end and remove the cotter pin using pliers.
Use a wrench to remove the nut securing the tie rod end to the steering knuckle.
Employ a steering wheel puller if necessary to separate the tie rod end from the knuckle.

5. Install the New Tie Rod End

Thread the new tie rod end into the steering rack to the same position as the old one for alignment purposes.
Secure it to the steering knuckle with the nut and replace the cotter pin.

6. Reassemble

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the manufacturer's specified torque value.
