Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Engage the parking brake for safety.

2. Inspect and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires to the manufacturer-recommended PSI found in the owner’s manual or on the door placard.

3. Check and Balance Tires

Remove the wheels from the vehicle using a socket set.
Mount each tire on a balancing machine to identify imbalance.
Add weights as necessary to balance the tires according to the machine's specifications.
Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (usually around 100-150 ft-lbs).

4. Inspect Suspension Components

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect control arms, bushings, and shocks for any signs of wear or damage.
Replace any worn or damaged components (e.g., control arms, bushings).

5. Verify Driveshaft and U-Joints

Inspect the driveshaft for any visible damage or bent sections.
Check u-joints for play or binding by manually moving them.
Replace any damaged driveshaft or u-joints as needed.

6. Perform Wheel Alignment

Use a wheel alignment machine to check the alignment settings.
Adjust camber, caster, and toe settings to manufacturer specifications.
Test drive to confirm that alignment adjustments have resolved the issue.
