Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat, stable surface.
Raise the vehicle using a jack and secure with jack stands.

2. Tire Balancing

Remove the wheels from the vehicle using a socket set.
Take the wheels to a tire shop for a dynamic balance check.
Reinstall the wheels after balancing and torque to manufacturer's specifications (typically 75-85 ft-lbs).

3. Tire Inspection and Replacement

Inspect all tires for uneven wear patterns or sidewall damage.
Replace any damaged tires with new ones of the same size and type.
Ensure all tires are inflated to the recommended pressure.

4. Wheel Alignment

Use an alignment machine to check and adjust the wheel alignment.
Adjust camber, caster, and toe settings according to manufacturer specifications.

5. Suspension Component Inspection and Repair

Visually inspect all suspension components for signs of wear or damage.
Replace any worn control arms, bushings, or struts as necessary.
Ensure all bolts are torqued to the manufacturer’s specifications.

6. Drivetrain Inspection

Inspect the driveshaft and CV joints for any excessive play or damage.
Replace any damaged components and ensure proper lubrication.
