Solution

1. Tire Inspection and Rotation

Inspect all tires for damage, uneven wear, or low pressure.
Rotate tires if uneven wear is found.
Balance tires if required.
Tools Required: Tire pressure gauge, tire changer, wheel balancer.

2. Check Wheel Bearings

Raise the vehicle using a jack and secure it with jack stands.
Grab the wheel at the 12 and 6 o'clock positions and shake. If there is excessive play, the bearing may need replacement.
Replace any faulty wheel bearings.
Tools Required: Socket set, bearing puller, torque wrench.

3. Inspect Driveshaft and CV Joints

Visually inspect the driveshaft for bent sections or damaged CV joints.
Check for any grease leaks around the CV boots.
Replace any damaged CV joints or driveshaft components.
Tools Required: Jack, jack stands, socket set, torque wrench.

4. Engine and Transmission Mount Inspection

Inspect the engine and transmission mounts for visible cracks, separation, or excessive wear.
Replace any damaged mounts to restore stability.
Tools Required: Socket set, torque wrench.

5. Rebalance and Align

After repairs, rebalance the wheels and perform a wheel alignment.
Ensure all components are tightened to manufacturer's specifications.
Tools Required: Wheel alignment machine, wheel balancer.
