Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as needed.
Secure the vehicle on jack stands to ensure stability.

3. Inspect and Replace Suspension Components

Shock Absorbers
- Remove the bolts securing the shock absorbers to the upper and lower mounts.
- Carefully detach the shock from the vehicle.
- Install the new shock absorber by reversing the removal steps. Torque the bolts to the manufacturer's specifications.
Control Arms/Bushings
- Remove the bolts securing the control arms to the chassis and the steering knuckle.
- Inspect the bushings for wear; if damaged, replace with new ones.
- Reinstall the control arms, ensuring proper alignment and torque specifications.

4. Tighten and Lubricate Components

Go through all suspension bolts and bushings, ensuring they are torqued to the manufacturer's specifications.
Apply a suitable lubricant to any moving parts or bushings to eliminate creaking noises.

5. Reassemble and Lower Vehicle

Remove jack stands and lower the vehicle using the hydraulic jack.
Reconnect the battery and ensure all tools are cleared from the undercarriage.
