Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool.

2. Tire Inspection and Balancing

Remove the Wheels: Use a jack to lift the vehicle and secure with jack stands. Remove the lug nuts with a socket set.
Inspect Tires: Check for uneven wear patterns, bulges, or punctures. Replace any damaged tires.
Balance Tires: Take the tires to a professional tire shop for balancing. Ensure they are balanced according to the manufacturer's specifications.

3. Wheel Alignment

Perform Alignment: Use a wheel alignment machine to check and adjust the alignment. Follow specifications from the manufacturer for angles (camber, caster, and toe).

4. Suspension Inspection

Examine Components: Visually inspect all suspension components, including control arms, bushings, struts, and shocks for signs of wear or damage.
Replace Damaged Parts: If any components are found to be worn or damaged, replace them with OEM or quality aftermarket parts.

5. Drivetrain Inspection

Inspect Driveshaft and CV Joints: Check for any play or damage in the driveshaft and CV joints. If found, replace as necessary.
Lubricate Components: Ensure that all moving parts are adequately lubricated according to manufacturer specifications.
