Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the area of concern.
Secure it with jack stands to ensure stability while working underneath.

3. Inspect and Lubricate Components

Suspension Bushings and Joints:
- Remove any dust covers if applicable.
- Apply a silicone-based lubricant to the bushings and joints.
- Ensure that all excess lubricant is wiped away to prevent attracting dirt.
Shock Absorbers/Struts:
- Inspect for any signs of oil leakage.
- If damaged, replace the shock absorbers/struts.

4. Tighten or Replace Hardware

Check all bolts and nuts securing the suspension components.
Use a torque wrench to tighten any loose bolts to the manufacturer's specifications.
Replace any corroded or damaged hardware as necessary.

5. Reassemble and Lower Vehicle

Reattach any dust covers or protective caps removed during inspection.
Carefully lower the vehicle from the jack stands and jack.
