2. Addressing Noisy Belts or Pulleys

Tools Required: Socket set, belt tensioner tool
Steps:
1. Remove the engine cover (if applicable) to access the serpentine belt.
2. Inspect the belt for signs of wear, fraying, or glazing.
3. If damaged, remove the old belt by relieving tension with the belt tensioner tool.
4. Install a new belt according to the routing diagram found on the engine bay.
5. Check pulleys for play or damage and replace if necessary.

3. Repair or Replace Wheel Bearings

Tools Required: Jack and jack stands, socket set, torque wrench
Steps:
1. Remove the wheel and inspect the brake assembly.
2. Use a socket set to remove the hub assembly or brake caliper (if needed).
3. Check the wheel bearing by manipulating it for any play or roughness.
4. If faulty, press out the old bearing and press in a new bearing using a bearing press.
5. Reinstall the hub assembly and wheel, ensuring proper torque specifications are followed.

4. Fixing Suspension Issues

Tools Required: Socket set, torque wrench, pry bar
Steps:
1. Inspect struts and shocks for leaks or damage.
