Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engaged in park mode.
Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

Use a hydraulic jack to lift the rear of the vehicle.
Secure the vehicle with jack stands to ensure safety.

3. Inspect and Replace Components

Inspect Shock Absorbers:
- Check for leaks or physical damage on the shock absorbers.
- If damaged, unscrew the mounting bolts using a socket set and remove the shock absorbers.
Inspect Control Arms and Bushings:
- Look for signs of wear or cracking on control arms and bushings.
- Replace any worn bushings by removing the control arm bolts and using a bushing removal tool.
Inspect Sway Bar Links:
- Inspect the sway bar links for play or damage.
- Replace if necessary by removing the nuts with a wrench and installing new links.

4. Reassemble and Lower the Vehicle

Reinstall all components in reverse order, ensuring to torque bolts to the manufacturer’s specifications (typically around 80-100 ft-lbs for suspension components).
Lower the vehicle from jack stands and remove the jack.

5. Reconnect Battery

Reconnect the battery terminals, ensuring they are tight and secure.
