Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electronic suspension components.

2. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Use a socket set to remove bolts securing the struts/shocks.
- Visually inspect for leaks, dents, or damage.
- If damaged, replace with manufacturer-approved parts.
Replace Bushings:
- Remove any components obstructing access to bushings.
- Use a bushing removal tool to extract old bushings.
- Install new bushings, ensuring they are seated properly.

3. Wheel Alignment and Balancing

Wheel Alignment:
- Use an alignment machine to check the alignment angles.
- Adjust camber, caster, and toe according to manufacturer specifications.
Wheel Balancing:
- Remove tires from the vehicle.
- Use a wheel balancing machine to check for imbalances.
- Add weights as necessary to achieve balance and re-mount tires.

4. Final Assembly

Reinstall any removed components and torque bolts to manufacturer specifications.
Reconnect the battery if it was disconnected.
Lower the vehicle back to the ground.
