Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Replacement

Sub-steps:
- Remove the wheel covers (if applicable) using a socket set.
- Loosen the lug nuts slightly (do not remove yet).
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the affected tires.
- Inspect the tires for uneven wear, bulges, or other damage.
- Replace any damaged tires with new ones of the same specifications.

Tools Required:

Jack and jack stands
Socket set
Tire pressure gauge

3. Wheel Balancing

Sub-steps:
- Take the tires to a tire shop for balancing, or use a static/dynamic balancer if available.
- Ensure weights are properly placed to achieve balance.
- Reinstall tires and torque lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

4. Wheel Alignment

Sub-steps:
- After balancing, check wheel alignment using an alignment machine.
- Adjust toe, camber, and caster angles as necessary to meet manufacturer's specifications.

Tools Required:

Alignment machine
Torque wrench

5. Suspension Inspection

Sub-steps:
- Visually inspect shocks, struts, and control arms for signs of wear or damage.
- Test for play in suspension components by attempting to move them by hand.
- Replace any worn components as needed, following the vehicle's service manual for specific procedures and torque settings.

Tools Required:

Wrenches and sockets
Torque wrench
