Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Lift Vehicle

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

3. Remove Rear Wheel

Use a lug wrench to loosen and remove the lug nuts from the rear wheel.
Remove the wheel to access the suspension components.

4. Inspect and Replace Components

Inspect Bushings: Check the condition of all bushings in the rear suspension. If worn, remove them using a bushing removal tool.
Replace Shocks/Struts: If shocks are leaking or damaged, remove the bolts securing the shock to the upper and lower mounts. Replace with new shocks, ensuring they are tightened to manufacturer specifications (typically around 30-35 Nm).
Check Springs: Inspect the coil springs for cracks or signs of sagging. Replace if necessary.
Reassemble: Reattach the rear wheel and torque the lug nuts to the manufacturer’s specifications (generally around 120 Nm).

5. Lower Vehicle

Carefully lower the vehicle back to the ground using the hydraulic jack.

6. Final Inspection

Reconnect the battery.
Conduct a final visual inspection of the suspension components to ensure everything is secure.
