Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Tire Inspection and Replacement (if necessary)

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Inspect all tires for uneven wear and ensure they are inflated to the manufacturer's specifications.
If any tire shows excessive wear or damage, replace them.
Reinstall tires and torque lug nuts to the specified value (usually 80-100 ft-lbs).

3. Balance and Alignment

Tools Required: Wheel balancer, alignment machine.
Remove the wheels and mount them on the wheel balancer to check for balance.
Adjust weights as necessary to achieve proper balance.
After balancing, perform a four-wheel alignment using the alignment machine, adjusting camber, caster, and toe settings as needed.

4. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, pry bar.
Inspect suspension components (control arms, bushings, struts) for wear.
Replace any worn or damaged parts, ensuring to torque all fasteners to the manufacturer’s specifications.

5. Driveshaft and CV Joint Inspection

Tools Required: Pliers, socket set.
Inspect the driveshaft for any signs of damage or wear.
Check CV joints for play or damage; replace if necessary.
