3
Check wheel alignment to ensure it is within manufacturer specifications.
4
Inspect suspension components, including struts, shocks, and bushings for wear or damage.
5

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent rolling.

2. Tire Balancing

Remove the wheel using a lug wrench.
Mount the wheel on a tire balancing machine and follow the manufacturer's instructions.
Add weights as needed to achieve balance.
Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Tire Inspection and Replacement

Visually inspect each tire for bulges, cuts, or irregular wear patterns.
Measure tread depth using a tread depth gauge; replace tires if below the legal limit (2/32 inches).
If tires are damaged or worn, remove and replace with new tires of the same specification.

4. Wheel Alignment

Using an alignment rack, attach the vehicle to the alignment machine.
Adjust toe, camber, and caster angles according to the manufacturer’s specifications.
Test drive the vehicle to confirm alignment.

5. Suspension Inspection and Repair

Visually inspect all suspension components for signs of wear, such as cracks or leaks.
Replace any worn parts like shocks, struts, or bushings as necessary.
Reassemble any components and ensure they are secure.
