Solution

1. Preparation

Gather tools and materials: tire pressure gauge, jack and jack stands, lug wrench, wheel balancer, alignment tools, and a torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Balancing

Sub-steps:
1. Check tire pressure using the tire pressure gauge; inflate to the recommended PSI if necessary.
2. Inspect tires for uneven wear, bulges, or damage; replace any tires that are excessively worn or damaged.
3. Remove the wheels using the lug wrench.
4. Use a wheel balancer to balance each wheel; add weights as needed to ensure proper balance.
5. Reinstall the wheels and torque lug nuts to the manufacturer’s specifications (typically 100-110 ft-lbs).

3. Suspension and Driveshaft Inspection

Sub-steps:
1. Inspect suspension components visually for any signs of wear, such as leaking shocks or worn bushings.
2. Check the driveshaft for any signs of damage or imbalance, ensuring that all bolts are tight and components are securely fastened.
3. If any components are damaged, replace them with OEM or equivalent parts.
4. Reassemble and ensure all fasteners are torqued to the manufacturer’s specifications.

4. Alignment Adjustment

Sub-steps:
1. Use alignment tools to check the alignment angles of the front and rear wheels.
2. Adjust the camber, caster, and toe angles to the manufacturer’s specifications as needed.
3. Test drive the vehicle to ensure the steering is centered and the vehicle tracks straight.
