Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety glasses and gloves for protection.

2. Remove Rear Wheel

Using a jack, lift the rear of the vehicle and secure it with jack stands.
Remove the rear wheel by loosening the lug nuts with a socket set.

3. Inspect and Replace Components

Shock Absorbers:
- Remove the bolts securing the shock absorber to the upper mount and lower control arm.
- Replace with new shock absorbers, ensuring they are properly torqued (typically around 40 Nm for the upper mount and 70 Nm for the lower).
Bushings:
- If bushings are worn, remove the suspension arm by unbolting the connections at both ends.
- Press out the old bushings and press in new ones, ensuring they are aligned properly.
Control Arms:
- Inspect control arms for signs of bending or damage.
- Replace if necessary, ensuring all bolts are torqued to the manufacturer’s specifications.

4. Reassemble and Install Rear Wheel

Reattach the rear suspension components in reverse order of removal.
Replace the rear wheel and hand-tighten the lug nuts.

5. Lower the Vehicle

Carefully lower the vehicle from the jack stands.
Use a torque wrench to fully tighten the lug nuts to the specified torque (typically 120 Nm).
