Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety warning: Always engage the parking brake and use wheel chocks.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove the wheel covers or hubcaps (if applicable).
2. Use a tire pressure gauge to check tire pressures; inflate to recommended PSI.
3. Perform a visual inspection for bulges, cuts, or uneven tire wear.
4. Replace any damaged or excessively worn tires with new tires of the same specification.

3. Check and Replace Wheel Bearings

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the hub.
3. Grasp the hub and check for side-to-side play; if present, the bearing may need replacement.
4. Remove the axle nut and bearing housing, then replace the old bearing with a new one.
5. Reassemble the hub and wheel, ensuring all fasteners are torqued to manufacturer specifications.

4. Verify Alignment and Suspension Components

Sub-steps:
1. Inspect suspension components (ball joints, tie rods, control arms) for wear or damage.
2. Replace any worn components.
3. Take the vehicle to a professional alignment shop to ensure proper alignment.
