Solution

1. Preparation

Gather tools: tire pressure gauge, jack and jack stands, wheel balancer, alignment machine, and torque wrench.
Verify that the vehicle is on a level surface and the engine is off.

2. Tire Inspection

Sub-steps:
1. Remove the hubcaps or wheel covers if applicable.
2. Inspect each tire for uneven wear patterns and damage.
3. Check tire pressure and inflate to the recommended PSI if necessary.

3. Wheel Balancing

Sub-steps:
1. Remove the tire and wheel assembly from the vehicle.
2. Mount the wheel on a wheel balancer.
3. Follow the balancer’s instructions to adjust weights until balanced.
4. Reinstall the wheel onto the vehicle, ensuring proper torque (typically 80-100 ft-lbs, but verify for specific model).

4. Wheel Alignment

Sub-steps:
1. If misalignment is detected, set up the vehicle on an alignment rack.
2. Adjust the camber, caster, and toe settings to match manufacturer specifications.
3. Perform test drives to verify alignment corrections.

5. Suspension Component Inspection

Sub-steps:
1. If issues persist, inspect all suspension components like tie rods, control arms, and bushings for wear or damage.
2. Replace any faulty components and ensure all fasteners are torqued to specifications.
