Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

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

3. Inspect and Replace Components

Shocks/Struts:
- Remove the lower shock mount bolts with a socket set.
- Lift the shock absorber out of the mounting bracket.
- Install the new shock absorber and torque the bolts to manufacturer specifications.
Bushings:
- Remove any necessary components to access the bushings (e.g., control arms).
- Use a bushing removal tool or press to replace worn bushings.
- Ensure proper alignment of the new bushings before reinstallation.
Springs:
- If necessary, remove the rear springs using a spring compressor.
- Inspect for cracks or damage, and replace if needed.
- Reinstall using the compressor and ensure proper seating in the mounts.

4. Reassemble and Lower the Vehicle

Reattach any components removed during inspection and replacement.
Lower the vehicle back to the ground and remove the jack stands.

5. Final Checks

Recheck all suspension bolts for tightness using a torque wrench.
Ensure that no tools are left under the vehicle.
