Solution

1. Preparation

Gather Tools and Parts: Collect necessary tools such as a socket set, torque wrench, and jack stands.
Safety Precautions: Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Jack Up the Vehicle: Use a hydraulic jack to lift the vehicle and support it with jack stands.
Remove Wheels: Take off the front and/or rear wheels to access the suspension components.

3. Inspect and Replace Components

Inspect Shock Absorbers/Struts: Check for leaks or damage; if necessary, replace with OEM parts.
- Remove Old Shock Absorber: Unbolt the upper and lower mounting points.
- Install New Shock Absorber: Align and secure the new shock absorber with recommended torque specifications.
Check Control Arms and Bushings: Inspect for wear; replace any damaged components.
- Remove Control Arm: Unbolt from frame and wheel hub.
- Install New Control Arm: Position and secure with specified torque values.

4. Reassemble

Reinstall Wheels: Put the wheels back on and hand-tighten the lug nuts.
Lower the Vehicle: Carefully remove jack stands and lower the vehicle to the ground.

5. Final Torque Check

Torque Lug Nuts: Tighten lug nuts to the manufacturer’s specification using a torque wrench.
