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

3. Inspect and Replace Components

Inspect Shock Absorbers:
- Check for any signs of leakage or physical damage.
- If damaged, remove the old shock absorber by loosening the mounting bolts (use a socket set).
- Install new shock absorbers, ensuring to torque the bolts to manufacturer specifications (typically around 50-70 ft-lbs).
Check Springs and Bushings:
- Inspect rear coil springs for cracks or sagging.
- Examine rubber bushings for wear; replace if they are cracked or deteriorated.
- To replace bushings, remove the component and use a bushing tool for installation.
