Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, tire pressure gauge, alignment machine, tire balancer.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Inspect Tires

Sub-steps:
1. Check tire pressure using a gauge; inflate to recommended PSI if necessary.
2. Visually inspect tires for uneven wear, bulges, or damage.
3. Replace any damaged tires if necessary.

3. Balance Wheels

Sub-steps:
1. Remove the wheels using the lug wrench.
2. Place the wheel on a tire balancer and spin to identify imbalance.
3. Add wheel weights as needed to achieve balance.
4. Reinstall balanced wheels and tighten lug nuts to manufacturer specifications (typically 100-150 ft-lbs).

4. Check Alignment

Sub-steps:
1. Use an alignment machine to check the wheel alignment settings (toe, camber, caster).
2. Adjust settings to meet manufacturer specifications.
3. Test drive the vehicle to ensure proper alignment and stability.

5. Inspect Suspension

Sub-steps:
1. Visually inspect suspension components (shocks, struts, control arms) for signs of wear or damage.
2. Replace any worn or damaged components with OEM parts.
3. Confirm that all mounting bolts are torqued to specification.
