Solution

1. Preparation

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

2. Raise the Vehicle

Use a floor jack to lift the front or rear of the vehicle.
Secure with jack stands to ensure stability.

3. Inspect and Replace Shock Absorbers (if necessary)

Sub-steps:
- Remove the bolts securing the top and bottom of the shock absorber using a socket set.
- Carefully detach the shock absorber from the vehicle.
- Compare the old shock with the new one to ensure correct sizing.
- Install the new shock absorber by reversing the removal process, ensuring all bolts are torqued to manufacturer specifications (typically around 30-50 ft-lbs).

4. Replace Worn Bushings or Mounts

Sub-steps:
- Identify any worn bushings or mounts during inspection.
- Use a bushing removal tool to remove the old bushings.
- Install the new bushings and ensure they are seated properly.
- Torque the mounting bolts to the specifications listed in the service manual.

5. Reassemble and Lower the Vehicle

Ensure all components are properly installed and torqued.
Remove jack stands and carefully lower the vehicle with the floor jack.
