Solution

1. Preparation

Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Wear safety glasses and gloves.

2. Tire Inspection

Remove the wheels using a socket set.
Inspect the tires for cracks, bulges, or uneven wear.
Replace any damaged tires with new ones if necessary.

3. Wheel Bearing Inspection

Spin the wheel by hand to check for roughness or noise.
If noise is present, remove the wheel bearing assembly using a bearing puller.
Replace the wheel bearings if they show signs of wear.

4. Suspension Component Check

Inspect shock absorbers and struts for fluid leaks or damage.
Check control arms, bushings, and sway bar links for wear.
Replace any worn suspension components with OEM parts.

5. Driveshaft and U-Joint Inspection

Inspect the driveshaft for any signs of damage or misalignment.
Check U-joints for movement by trying to rock them back and forth.
If U-joints are worn, replace them using a U-joint press.

6. Brake Component Check
