Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Use a hydraulic floor jack to lift the front and/or rear of the vehicle.
Secure the vehicle on jack stands to ensure safety while working underneath.

3. Inspect Suspension Components

Control Arm Bushings: Check for cracks or tears. If damaged, replace with OEM parts.
Strut Mounts: Inspect for wear. If the strut mounts appear worn, replace them.
Shock Absorbers: Look for leaks or signs of oil degradation. Replace if necessary.

4. Tighten Loose Components

Use a torque wrench to check and tighten all suspension-related bolts to the manufacturer’s specifications.
Refer to the service manual for specific torque values for each component.

5. Reassemble and Lower the Vehicle

Once all inspections and repairs are complete, reassemble any components that were removed.
Carefully lower the vehicle back to the ground using the hydraulic jack.
