Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Tire Inspection and Replacement

Remove the wheel covers (if applicable) and loosen lug nuts slightly (do not remove).
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheels.
Inspect the tire tread for uneven wear patterns and check for bulges or punctures.
If any tires are damaged or excessively worn, replace them with new tires.

3. Wheel Balancing

Mount the tires on a wheel balancing machine.
Follow the machine's instructions to balance each tire.
If imbalances are detected, adjust with appropriate weights until balanced.

4. Wheel Alignment

Use an alignment machine to check the alignment settings.
Adjust the camber, caster, and toe as needed to meet manufacturer specifications.
Test drive after alignment to ensure the vehicle tracks straight.

5. Suspension Component Replacement (if necessary)

Inspect suspension components for wear.
If any components like bushings or ball joints are damaged, remove and replace them using appropriate tools.
Tighten all fasteners to manufacturer torque specifications.
