Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface and secure it with wheel chocks.

2. Raise the Vehicle

Use a floor jack to lift the vehicle and secure it on jack stands.
Remove the wheels to access the suspension components.

3. Inspect and Replace Shocks/Struts

Inspect Existing Shocks/Struts:
- Check for any signs of oil leakage.
- Assess the physical condition of the shocks/struts for dents or rust.
Replace Shocks/Struts:
1. Remove the bolts securing the shocks/struts to the vehicle.
2. Detach any mounting hardware and remove the old shocks/struts.
3. Install the new shocks/struts in reverse order of removal.
4. Torque the bolts to manufacturer specifications (usually around 40-50 ft-lbs).

4. Check and Adjust Suspension Alignment

After replacing the shocks/struts, have the alignment checked and adjusted by a professional.
Ensure that caster, camber, and toe settings are within specifications.

5. Reinstall Wheels and Lower Vehicle

Reinstall the wheels and torque the lug nuts to the specified torque (typically 80-100 ft-lbs).
Lower the vehicle to the ground.
