Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and engage the parking brake.
Gather all necessary tools and parts for the repair.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as necessary.
Secure the vehicle on jack stands for safety.

3. Inspect and Replace Components

Inspect the Shock Absorbers:
1. Check for leaks or physical damage.
2. If defective, remove the bolts securing the shock absorber to the upper and lower mounting points using a socket set.
3. Install new shock absorbers, ensuring they are torqued to manufacturer specifications (usually around 40-50 ft-lbs).
Check Suspension Bushings:
1. Inspect all control arm and sway bar bushings for cracks or excessive wear.
2. If damaged, use a bushing removal tool to replace them.

4. Tighten Loose Bolts

Check all suspension bolts and fasteners.
Tighten any loose bolts to the specified torque values, typically around 30-70 ft-lbs depending on the component.

5. Reassemble and Lower the Vehicle

After all components are inspected and repaired, remove jack stands and lower the vehicle.
Perform a final inspection to ensure all tools are accounted for and everything is securely fastened.
