Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Tires (if necessary)

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench.
Sub-steps:
1. Check each tire's pressure and inflate to manufacturer specifications if low.
2. Examine tires for uneven wear; replace if tread depth is below 2/32 inches or if there are bulges or punctures.
3. If tire replacement is necessary, use a lug wrench to loosen the lug nuts, raise the vehicle with a jack, secure with jack stands, and remove the tire.
4. Install the new tire, hand-tighten the lug nuts, lower the vehicle, and torque the lug nuts to manufacturer specifications.

3. Inspect Exhaust System

Tools Required: Socket set, exhaust pipe hanger tool.
Sub-steps:
1. Inspect the exhaust system for any visible cracks, rust, or loose components.
2. Tighten any loose bolts or clamps to secure the exhaust system.
3. Replace any damaged sections of the exhaust pipe or muffler as necessary.

4. Check Wheel Bearings

Tools Required: Jack, jack stands, socket set, torque wrench.
Sub-steps:
1. Raise the vehicle and remove the wheel to access the hub assembly.
2. Wobble the wheel to check for excessive play indicating a worn wheel bearing.
3. If play is present, remove the hub assembly and replace the wheel bearing using a press.
4. Reassemble the hub and wheel, torquing to manufacturer specifications.
