Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure safety by wearing gloves and safety goggles.

2. Tire Inspection and Balancing

Remove the wheel covers if applicable.
Loosen the lug nuts on the affected wheel using a lug wrench.
Lift the vehicle with a jack and secure it with jack stands.
Remove the wheel and inspect the tire for any visible damage.
Take the tire to a tire shop for balancing if necessary.
Reinstall the wheel, ensuring lug nuts are tightened to the manufacturer’s torque specifications (usually around 80-100 ft-lbs).

3. Suspension and Alignment Check

Inspect all suspension components visually for signs of wear (e.g., bushings, ball joints).
Replace any damaged components as needed.
Use an alignment machine to check and adjust the wheel alignment to manufacturer specifications.

4. Drivetrain Inspection

Inspect the CV joints for any signs of grease leakage or damage.
Check the driveshaft for any unusual play or damage.
Replace any faulty components as needed.
