Solution

1. Tire Inspection and Maintenance

Sub-steps:
1. Check tire pressure using a tire pressure gauge and inflate to manufacturer's specifications if necessary.
2. Inspect tires for uneven wear patterns indicating a possible alignment issue.
3. Rotate tires if uneven wear is found to promote even wear.

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Place the wheels on a wheel balancer to identify any imbalances.
3. Add wheel weights as needed to balance each wheel, then reattach the wheels to the vehicle.

3. Wheel Alignment

Sub-steps:
1. Use an alignment machine to check wheel alignment.
2. Adjust camber, caster, and toe settings to manufacturer specifications.
3. Test drive the vehicle to confirm that pulling issues are resolved.

4. Suspension Inspection

Sub-steps:
1. Visually inspect suspension components (shocks, struts, bushings) for wear or damage.
2. Replace any worn components with OEM parts to restore proper handling and ride quality.

5. Driveshaft and Axle Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of damage or imbalance.
2. Check CV joints for wear and replace if necessary.
3. Ensure that all fasteners are tight and that the driveshaft is properly secured.
