Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, suspension grease.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the battery to ensure safety while working on components.

2. Inspect and Replace Components

- Remove lower bolts securing the rear shocks using a socket set.
- Check for leaks or physical damage on the shocks.
- If damaged, replace with OEM or aftermarket shocks, following manufacturer's instructions for installation.
Check Springs:
- Inspect coil springs for cracks or deformities.
- If damaged, remove the spring by decompressing it with a spring compressor and replace it with a new spring.

3. Tighten and Grease

Tighten Fasteners:
- Inspect all mounting bolts and nuts for tightness.
- Use a torque wrench to tighten to the specification found in the service manual.
Grease Bushings:
- Check all bushings for wear and tear.
- Apply suspension grease or replace bushings if they are worn.
