Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Balancing

Tools Required: Wheel balancer, jack, jack stands
Lift the vehicle using a jack and secure it with jack stands.
Remove the tires and mount them on a wheel balancer.
Follow the balancer's instructions to adjust weights accordingly and ensure each tire is balanced.
Reinstall the tires and lower the vehicle.

3. Tire Inspection and Replacement

Inspect each tire for bulges or uneven wear.
If any tire is damaged or excessively worn, replace it with a new tire of the same specification.
Ensure the new tires are properly inflated according to manufacturer specifications.

4. Wheel Alignment

Tools Required: Alignment machine
Take the vehicle to an alignment shop.
Adjust the alignment settings to the manufacturer's specifications.
Confirm that the steering wheel is centered after adjustments.

5. Suspension Inspection and Repair

Check all suspension components, including control arms, bushings, and struts.
Replace any worn or damaged parts using manufacturer-recommended parts.
Re-torque all suspension bolts to the specified values.

6. Drivetrain Inspection and Repair

Inspect the driveshaft for any signs of wear or play.
If a CV joint is damaged, replace it with an OEM part, ensuring proper installation.
Check the differential fluid levels and replace fluid if necessary.

7. Brake Component Inspection

Inspect brake rotors for warping or uneven wear.
If rotors are warped, replace them and ensure calipers are functioning correctly.
Reassemble brake components and ensure everything is tight and secure.
