Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and engage the parking brake.
Gather necessary tools and parts.
Tools Required: Floor jack, jack stands, torque wrench, tire pressure gauge, wheel balancer, alignment tool.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers if applicable.
2. Use a tire pressure gauge to check each tire's pressure, and inflate to recommended levels if necessary.
3. Inspect tires for visible damage; replace any tires that show significant wear or deformity.
4. If tires are in good condition, proceed to balance the wheels using a wheel balancer.

3. Wheel Balancing

Sub-steps:
1. Mount the wheel on the balancer and follow the manufacturer's instructions.
2. Add or remove weights as indicated by the balancer until the wheel is balanced.
3. Reinstall the balanced wheel onto the vehicle, ensuring to torque lug nuts to manufacturer specifications (typically 100-120 ft-lbs).

4. Wheel Alignment

Sub-steps:
1. Place the vehicle on an alignment rack.
2. Adjust the front and rear toe, camber, and caster angles according to the manufacturer's specifications.
3. Verify all adjustments and ensure they fall within the acceptable ranges.

5. Suspension Component Inspection

Sub-steps:
1. Visually inspect all suspension components for signs of wear or damage.
2. Replace any worn tie rods, control arms, or bushings as necessary.
3. Reassemble any removed components and ensure all fasteners are torqued to specifications.
