Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Inspect and Replace Tires (if necessary)

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Sub-steps:
1. Use a tire pressure gauge to check the pressure in all tires and inflate to the recommended PSI.
2. Visually inspect the tread for uneven wear; if uneven wear is found, consider rotating or replacing tires.
3. If tire replacement is necessary, loosen the lug nuts, raise the vehicle with a jack, and secure with jack stands.
4. Remove the lug nuts completely and replace the tire with a new or properly balanced tire.
5. Reinstall lug nuts and tighten to the manufacturer's torque specification (typically 80-100 lb-ft).

3. Inspect and Replace Wheel Bearings (if necessary)

Tools Required: Socket set, torque wrench, bearing puller, grease.
Sub-steps:
1. Remove the wheel and tire assembly.
2. Remove the brake caliper and rotor to access the wheel hub.
3. Inspect the wheel bearing for play by manually rotating it; if it feels rough or has excessive play, it needs replacement.
4. Use a bearing puller to remove the old bearing from the hub.
5. Clean the hub area and install the new bearing with appropriate grease.
6. Reassemble the brake rotor and caliper, ensuring all bolts are torqued to specification.

4. Check Drivetrain Components

Tools Required: Visual inspection tools (flashlight), socket set.
Sub-steps:
1. Inspect the CV joints for any signs of damage or torn boots.
2. Check the differential fluid level and condition; replace if necessary.
3. Inspect the driveshaft and associated components for wear or damage.
