Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the suspension components.

4. Inspect and Replace Suspension Components

Inspect Shock Absorbers/Struts:
- Check for oil leakage, dents, or physical damage.
Replace if necessary:
- Use a socket set to remove mounting bolts.
- Install the new shock absorber/strut and torque bolts to manufacturer specifications (usually around 30-40 ft-lbs).
Inspect Bushings and Control Arms:
- Check for cracks or separation in rubber bushings.
Replace if necessary:
- Use a socket set to remove the control arm bolts.
- Install the new control arm with bushings, ensuring proper alignment, and torque bolts as specified.

5. Reassemble

Reattach the wheel and tighten lug nuts in a star pattern to ensure even tightening.
Lower the vehicle back to the ground and reconnect the negative battery terminal.
