Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.

2. Inspect and Replace Wheel Bearings (if needed)

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel by loosening lug nuts with a socket wrench.
3. Inspect the wheel bearing for play or noise by spinning the hub.
4. If defective, remove the brake caliper and rotor.
5. Use a bearing puller to extract the old bearing from the hub assembly.
6. Press in the new bearing, ensuring it is seated correctly.
7. Reassemble the rotor and caliper, then reattach the wheel and lower the vehicle.

3. Inspect and Replace Tires (if needed)

Sub-steps:
1. Check tire tread depth using a tread depth gauge.
2. Inspect for bulges, cuts, or foreign objects.
3. If replacement is necessary, use a tire iron to loosen lug nuts and remove the wheel.
4. Install new tires, ensuring they are properly inflated to manufacturer specifications.
5. Reattach the wheel and torque lug nuts to the recommended specification (typically 80-100 ft-lbs).

4. Examine and Repair Exhaust System (if needed)

Sub-steps:
1. Visually inspect the exhaust system from the engine to the tailpipe for rust or holes.
2. Use a rubber mallet to tap on exhaust pipes and muffler; listen for hollow sounds indicating corrosion.
3. Replace any damaged sections of the exhaust with new pipes or clamps as necessary.
