Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection and Replacement (if necessary)

Tools Required: Jack, jack stands, lug wrench
Remove each tire and inspect for damage, bulges, or uneven wear.
If tires are worn or damaged, replace them with new tires of the same size and specifications.
Reinstall tires, ensuring proper torque (generally 75-100 ft-lbs depending on the model).

3. Wheel Balancing

Tools Required: Wheel balancer
Mount each wheel on a balancer and follow the machine's instructions to balance the wheel.
Adjust weights as necessary to achieve proper balance.

4. Wheel Alignment

Tools Required: Alignment machine
Set the vehicle on the alignment machine and follow the manufacturer’s specifications for alignment settings.
Adjust camber, toe, and caster angles as needed to achieve proper alignment.

5. Suspension Inspection and Repair (if necessary)

Tools Required: Socket set, torque wrench
Inspect all suspension components including ball joints, tie rods, and bushings for play or damage.
Replace any worn components and ensure all fasteners are torqued to manufacturer specifications.
