Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues while working.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using a socket set.

3. Remove Old Shock Absorbers

Locate the top and bottom mounting bolts of the shock absorbers.
Use a socket wrench to remove the top mounting bolts first, then the bottom bolts.
Carefully take out the old shock absorbers from the vehicle.

4. Install New Shock Absorbers

Position the new shock absorber in place.
Insert the bottom bolt first and tighten to the manufacturer's specified torque (usually around 35-45 ft-lbs).
Attach the top bolts and tighten them as well, following the manufacturer's torque specifications.
