Solution

1. Preparation

Gather tools required and park the vehicle on a level surface.
Ensure the vehicle is securely lifted using jack stands and the wheels are off the ground.
Tools Required: Jack, jack stands, socket set, pry bar, torque wrench, and lubricant.

2. Remove and Inspect Damaged Components

Remove wheels: Use a socket set to loosen and remove the lug nuts and take off the wheels.
Inspect bushings and mounts: Check for cracks, wear, or deterioration in rubber bushings around control arms and struts. Replace any that are damaged.
Check strut and shock absorbers: Look for leaks or signs of wear. If they are worn out, they should be replaced.

3. Lubrication

Lubricate bushings: Apply suitable lubricant to the rubber bushings and any pivot points in the suspension system. Ensure that the lubricant is compatible with rubber.
Reassemble components: After lubrication, reassemble any components that were removed for inspection.

4. Reinstallation

Reinstall wheels: Place the wheels back onto the vehicle and hand-tighten the lug nuts.
Lower the vehicle: Carefully lower the vehicle back to the ground.
Torque lug nuts: Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (typically around 76 lb-ft for Toyota Corolla).
