Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Raise the vehicle securely with jack stands.

2. Inspect Suspension Components

Strut and Shock Absorber Inspection:
- Remove any covers or shields.
- Check for oil leakage on shocks/struts.
- Verify that they are securely mounted.
Control Arm and Bushing Inspection:
- Inspect control arms for cracks or bends.
- Check bushings for cracks or excessive wear.

3. Tighten Loose Components

Using a torque wrench, tighten all suspension bolts and nuts to the manufacturer's specified torque values.
Replace any damaged hardware as necessary.

4. Replace Worn Components

If any components are found to be worn or damaged, replace them as follows:
- Shock Absorbers:
  1. Remove the bolts securing the shock absorber.
  2. Detach the shock from the mounting points.
  3. Install the new shock absorber and secure it with bolts.
- Control Arm Bushings:
  1. Remove the control arm from the vehicle.
  2. Press out the old bushings and install new ones.
  3. Reinstall the control arm and secure it.

5. Reassemble and Lower Vehicle

Reattach any covers or shields that were removed during the inspection.
Lower the vehicle back to the ground and remove jack stands.
