Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted with jack stands.

2. Tire Balancing

Remove the front tires using a socket set.
Mount tires on a tire balancing machine to check for imbalance.
Add wheel weights as necessary to balance the tires properly.
Reinstall tires and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Wheel Alignment

Use an alignment machine to check the wheel alignment.
Adjust camber, caster, and toe angles as required to meet manufacturer specifications.

4. Suspension Inspection and Repair

Inspect suspension components for damage or wear.
Replace any worn or damaged components, such as shocks or bushings.
Ensure all fasteners are tightened to the specified torque values.

5. Driveline Inspection

Check u-joints for play by moving the driveshaft up and down.
If u-joints are worn, replace them by removing the driveshaft and using a press to install new joints.
Inspect the driveshaft for any signs of damage; replace if necessary.
