Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety gear, including gloves and safety glasses.

2. Tire Inspection and Balancing

Tools Required: Tire balancer, torque wrench, jack, jack stands.
Remove the affected tires using a lug wrench.
Inspect tires for punctures, bulges, or uneven wear.
If tires are worn or damaged, replace them.
Balance tires using a tire balancer and reinstall them, tightening the lug nuts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).

3. Suspension and Drivetrain Checks

Tools Required: Socket set, pry bar, torque wrench.
Inspect suspension components for play or wear:
- Check control arm bushings, ball joints, and tie rod ends.
- Replace any worn components.
Inspect the driveshaft for damage or misalignment:
- Ensure that the CV joints are not damaged.
- If damaged, replace the driveshaft assembly.

4. Final Inspection

After repairs, re-check wheel lug nut torque.
Conduct a visual inspection to ensure all components are securely installed and in good condition.
