Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Check each tire for proper inflation (refer to the recommended PSI in the owner’s manual).
2. Inspect tread depth with a tread depth gauge; replace any tires with less than 2/32 inches of tread.
3. Replace damaged tires as necessary.

2. Wheel Balancing

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle using a socket set.
2. Mount the wheel on a wheel balancer.
3. Add weights as necessary to achieve balance, ensuring the assembly is within manufacturer specifications.
4. Reinstall the wheel and torque to specifications (typically around 80-100 Nm).

3. Suspension Component Inspection and Replacement

Sub-steps:
1. Raise the vehicle using a lift or jack stands and remove the wheel.
2. Visually inspect shock absorbers for leaks and bushings for wear.
3. Replace any worn components; use OEM parts for best results.
4. Reassemble and torque components to specifications.

4. Wheel Alignment

Sub-steps:
1. Drive the vehicle to an alignment shop with a four-wheel alignment system.
2. Adjust toe, camber, and caster settings to match manufacturer specifications.
3. Test the alignment post-adjustment to ensure stability at high speeds.
