Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack, jack stands, torque wrench, tire pressure gauge, wheel balancer (if available).

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure in all tires.
Inflate or deflate tires to meet the manufacturer's recommended pressure.
Safety Warning: Ensure the vehicle is stable on jack stands before working under it.

3. Inspect Tires

Visually examine each tire for damage, uneven wear, or bulges.
If any tires are damaged, replace them with new tires of matching specifications.

4. Wheel Balancing

Remove the wheel and tire assembly from the vehicle.
Use a wheel balancer to check if the wheel is out of balance; add or remove weights as necessary.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (typically around 90-100 ft-lbs).

5. Suspension Inspection

Inspect suspension components, including control arms, struts, and bushings for wear or damage.
Replace any worn or damaged components to restore proper handling and stability.
