Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.
Disconnect the battery if applicable for electronic components.

2. Replace Worn Components

Shocks/Struts Replacement
- Use a socket set to remove the bolts securing the rear shocks to the mounts.
- Carefully detach the shock from the mounting points.
- Install the new shock, ensuring it is oriented correctly and tighten bolts to the manufacturer’s specifications (usually around 35-45 ft-lbs).
Bushings Replacement
- Remove the suspension arm if necessary using a wrench to detach bolts.
- Press out the old bushings using a bushing removal tool.
- Install new bushings, ensuring they are seated properly in the suspension arm.

3. Tighten Loose Fasteners

Inspect and tighten all suspension-related bolts and fasteners.
Use a torque wrench to ensure that all bolts are tightened to the manufacturer’s torque specifications.

4. Reassemble and Lower Vehicle

Once all components have been repaired or replaced, reassemble any disassembled parts.
Lower the vehicle back to the ground and remove jack stands.
