Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks.
Disconnect the negative battery terminal to ensure safety while working.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheels using a socket set.

3. Inspect and Replace Components

Shocks/Struts Replacement:
1. Remove the lower shock mounting bolt using a socket set.
2. Detach the upper shock mount by removing the nuts located in the trunk or wheel well.
3. Install the new shock absorber by reversing the removal steps.
4. Torque the upper and lower mounting bolts to the manufacturer's specifications (typically 30-40 ft-lbs for lower bolts, 15-20 ft-lbs for upper bolts).
Bushing Replacement:
1. Remove any necessary components obstructing access to the bushings (like sway bar links).
2. Use a pry bar to remove old bushings from the control arms or subframe.
3. Install new bushings, ensuring they are oriented correctly.
4. Reassemble any components removed during this process and torque to specification.

4. Reassemble and Lower the Vehicle

Reinstall the rear wheels and tighten the lug nuts to the specified torque (usually 90 ft-lbs).
Carefully lower the vehicle to the ground and remove jack stands.

5. Final Inspection

Reconnect the negative battery terminal.
Double-check all fasteners and ensure everything is secure.
