Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery to ensure safety while working on electronic components.

2. Raise the Vehicle

Use a jack to lift the rear of the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Shock Absorbers

Tools Required: Socket set, torque wrench, pry bar.
Remove the lower shock absorber bolts using the socket set.
Detach the upper mount of the shock absorber.
Inspect the shock absorbers for leaks or signs of wear.
If necessary, replace the shock absorbers with new parts.
- Sub-steps:
  - Align the new shock absorber in place and secure the upper mount.
  - Torque the upper and lower bolts to the manufacturer's specifications (typically around 50-70 Nm, check service manual).

4. Check and Replace Bushings

Tools Required: Pry tool, socket set, torque wrench.
Inspect the bushings in the control arms and rear axle.
If cracked or deteriorated, remove the control arm bolts and use the pry tool to remove old bushings.
Install new bushings and reassemble the control arms.
- Sub-steps:
  - Torque the control arm bolts to the specified value (consult service manual).

5. Reassemble and Lower the Vehicle

Recheck all components for proper installation and torque.
Lower the vehicle off the jack stands using the jack.
Reconnect the battery.
