Solution

1. Preparation

Tools Required: Floor jack, jack stands, wheel chocks, socket set, torque wrench, stethoscope, lubricants (silicone grease or appropriate lubricant).
Ensure the vehicle is parked on a flat surface and the parking brake is engaged. Disconnect the battery if electrical components will be handled.

2. Raise and Secure the Vehicle

Use a floor jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to ensure stability.
Remove the wheels to access suspension components.

3. Inspect and Replace Worn Components

Visually inspect shock absorbers for leaks or physical damage.
Check coil springs for cracks or deformation; replace if necessary.
Inspect bushings for cracks or excessive wear; replace if they are worn out.
If any bolts are found loose, tighten them to the manufacturer's specifications using a torque wrench.

4. Lubricate Components

Apply silicone grease to the bushings and any pivot points in the suspension assembly.
Ensure that any rubber components are adequately lubricated to prevent squeaking.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle back to the ground using the floor jack.
Torque the lug nuts to the specified value in a criss-cross pattern.
