1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Lift the Vehicle

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

3. Remove the Old Shock Absorber

Tools Required: Socket set, wrench, torque wrench.
Locate the upper and lower mounting bolts of the shock absorber.
Use the socket set to remove the lower bolt first, followed by the upper bolt.
Carefully remove the shock absorber from its mounting points.

4. Inspect and Clean

Check the shock absorber mounting points for wear or damage.
Clean any debris or rust from the mounting surfaces using a wire brush.

5. Install the New Shock Absorber
