Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery to prevent electrical issues during repairs.

2. Tire Inspection and Balancing

Sub-steps:
1. Inspect each tire for bulges, punctures, or uneven wear.
2. If any tire issues are found, replace or repair the affected tire.
3. Use a tire balancer to check and balance all four tires.
4. Reinstall the balanced tires and torque lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Drivetrain Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of damage or excessive play.
2. Check CV joints for signs of wear or torn boots.
3. If any components are damaged, replace them following manufacturer specifications.
4. Reassemble any removed components, ensuring all bolts are torqued to the correct specifications.

4. Wheel Alignment

Sub-steps:
1. Perform a four-wheel alignment using an alignment machine.
2. Adjust toe, camber, and caster angles as necessary to manufacturer specifications.
3. Test drive the vehicle to ensure proper handling and alignment.
