Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure it with jack stands for safety.

3. Inspect and Replace Shock Absorbers

Tools Required: Socket set, torque wrench, wrench set, pry bar.
Remove the lower mounting bolts of the shock absorber using the socket set.
Remove the upper mounting bolts from inside the trunk or wheel well area.
Extract the old shock absorber.
Install the new shock absorber by reversing the removal process, ensuring all bolts are torqued to manufacturer specifications (typically around 15-20 ft-lbs for upper bolts and 40-50 ft-lbs for lower bolts).

4. Check and Replace Springs (if necessary)

Tools Required: Spring compressor (if replacing coil springs), socket set.
If the springs are damaged or sagging, use a spring compressor to safely remove them.
Replace with new springs and ensure they are seated properly.
Reassemble the suspension components.

5. Reassemble and Lower the Vehicle

Reinstall any components that were removed during inspection.
Double-check all bolts for proper torque.
Carefully lower the vehicle back to the ground.
