Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a floor jack to lift the rear of the vehicle.
Place jack stands under the vehicle’s rear frame to ensure stability.

3. Remove Wheel

Use a lug wrench to remove the rear wheel nuts.
Take off the rear wheel and set it aside.

4. Remove Old Shock Absorbers

Locate the top and bottom mounting bolts of the shock absorber.
Use a socket set to remove the upper bolt from the top mount.
Remove the lower bolt using a wrench and carefully pull out the shock absorber.

5. Install New Shock Absorbers

Position the new shock absorber in place.
Insert the lower mounting bolt and tighten to the manufacturer’s specified torque (typically around 40-50 Nm).
Secure the upper mount by tightening the upper bolt.

6. Replace Bushings (if necessary)

If bushings are worn, remove them using a bushing removal tool.
Install new bushings by pressing them into place using a suitable tool or by hand, ensuring they are seated properly.

7. Reassemble

Reattach the rear wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the floor jack.
Once on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specification (usually around 120 Nm).
