Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Set the parking brake and lift the vehicle using a jack and secure with jack stands.

2. Inspect and Replace Brake Pads (if necessary)

Tools Required:
- Socket set
- Brake caliper tool
- Torque wrench
Instructions:
1. Remove the wheel to access the brake assembly.
2. Use the socket set to remove caliper bolts and carefully detach the caliper, supporting it with a wire.
3. Inspect brake pads for thickness; if worn below 3mm, replace.
4. Remove old pads and install new ones, ensuring they are properly seated.
5. Reattach the caliper and torque bolts to the manufacturer’s specification (typically around 25-30 ft-lbs).
6. Replace the wheel and lower the vehicle.

3. Inspect and Replace Serpentine Belt (if necessary)

Tools Required:
- Wrench or socket set
Instructions:
1. Locate the serpentine belt tensioner and release tension using a wrench.
2. Remove the old serpentine belt from the pulleys.
3. Inspect pulleys for damage or wear.
4. Install the new serpentine belt, following the belt routing diagram typically found on a sticker in the engine bay.
5. Release the tensioner to apply tension to the new belt.

4. Inspect and Replace Wheel Bearings (if necessary)

Tools Required:
- Socket set
- Torque wrench
- Bearing puller (if necessary)
Instructions:
1. Remove the wheel and brake components to access the hub.
2. Inspect the wheel bearing by spinning the hub; listen for grinding or roughness.
3. If defective, remove the hub assembly and use a bearing puller to extract the old bearing.
4. Install the new bearing and reassemble the hub and brake components.
5. Torque all bolts to manufacturer specifications.
