Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, wheel balancing equipment, alignment tools, and suspension inspection tools.
Ensure the vehicle is parked on a flat, stable surface, and engage the parking brake.

2. Tire Inspection and Pressure Check

Sub-steps:
1. Remove the wheel covers if necessary.
2. Inspect each tire for signs of uneven wear or damage.
3. Use a tire pressure gauge to check and adjust tire pressures according to manufacturer specifications (usually found on the driver's door jamb).

3. Wheel Balancing

Sub-steps:
1. Remove the affected wheels using a lug wrench.
2. Mount the wheels on a wheel balancing machine.
3. Follow the machine's instructions to balance the wheels and adjust weights as necessary.

4. Wheel Alignment

Sub-steps:
1. Set the vehicle on an alignment rack.
2. Adjust the alignment angles (toe, camber, and caster) to meet manufacturer specifications.
3. Test drive the vehicle to ensure proper alignment.

5. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect shocks, struts, and bushings for any signs of wear or leakage.
2. If any components are damaged, replace them with OEM parts.
3. After replacing components, ensure all bolts are torqued to manufacturer specifications.
