Solution

1. Tire Inspection and Replacement

Remove the wheels using a socket set.
Inspect each tire for uneven wear, bulges, or punctures.
Replace any damaged tires with new ones, ensuring they are of the same specifications.
Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).

2. Wheel Alignment

After ensuring the tires are in good condition, take the vehicle to a professional alignment shop.
Perform a 4-wheel alignment to ensure all wheels are properly aligned according to manufacturer specifications.
Adjust camber, caster, and toe settings as necessary.

3. Suspension Component Replacement

If any suspension components are found to be damaged during inspection, replace them.
- For example, if struts are worn, remove the strut assembly using a socket set and strut spring compressor.
- Install new struts and torque to specified values.
Inspect and replace any worn bushings or control arms if necessary.

4. Drivetrain Inspection and Repair

If vibrations persist, inspect the driveshaft and axles for damage or imbalance.
Replace any worn or damaged CV joints or driveshaft components.
Ensure all fasteners and bolts are tightened to manufacturer specifications.
