Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Remove all four tires using a lug wrench.
2. Inspect each tire for bulges, cuts, or uneven tread wear.
3. Replace any damaged or excessively worn tires with new ones.
4. Ensure all tires are of the same size and type for optimal performance.

2. Wheel Balancing

Sub-steps:
1. Mount the tires on a wheel balancer.
2. Spin the wheels to identify imbalances.
3. Add wheel weights as necessary to balance each wheel.
4. Reinstall the balanced wheels onto the vehicle and torque the lug nuts to manufacturer specifications (typically 80-110 ft-lbs).

3. Wheel Alignment

Sub-steps:
1. Drive the vehicle onto a wheel alignment rack.
2. Use alignment equipment to measure the angles of the wheels.
3. Adjust the alignment settings for camber, caster, and toe to meet factory specifications.
4. Test drive the vehicle after adjustments to ensure proper alignment.

4. Suspension Component Inspection and Replacement

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect control arms, bushings, and struts for any signs of wear or damage.
3. Replace any worn suspension components with OEM or quality aftermarket parts.
4. Reassemble and lower the vehicle back to the ground.
