Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Tire Balancing

Remove the wheel from the affected side(s) using a socket set.
Take the wheel to a tire shop or use a tire balancing machine to check for imbalance.
Add or adjust wheel weights as necessary based on the machine's readings.

3. Tire Inspection and Replacement (if necessary)

Inspect the tires for bulges, punctures, or uneven wear.
If tires are damaged or excessively worn, replace them with new tires of the same specifications.
Ensure proper alignment of the new tires and check for correct inflation before reinstallation.

4. Suspension and Steering Component Inspection

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect tie rods, ball joints, and control arms for any signs of play or damage.
Replace any worn or damaged parts with OEM or high-quality aftermarket components.

5. Brake System Check

Inspect brake rotors for warping by measuring thickness with a micrometer.
If warped, replace the rotors and check brake pads for even wear; replace if necessary.
Reassemble all components and ensure everything is torqued to manufacturer specifications.
