Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery terminal (negative) for safety.

2. Inspect and Replace Brake Pads (if applicable)

Sub-steps:
1. Remove the wheel using a socket set.
2. Use a torque wrench to remove caliper bolts.
3. Pull the caliper away from the rotor and secure it with a bungee cord.
4. Remove old brake pads and inspect for wear.
5. Install new brake pads ensuring they fit snugly.
6. Reassemble the caliper and wheel, torque bolts to manufacturer specifications (typically around 80 ft-lbs).

3. Inspect and Replace Serpentine Belt (if applicable)

Sub-steps:
1. Locate the serpentine belt tensioner and use a ratchet to relieve tension.
2. Remove the old belt from the pulleys.
3. Compare the old belt with the new belt for size and specification.
4. Route the new belt according to the belt routing diagram usually found on a sticker under the hood.
5. Reapply tension to the belt and ensure it sits correctly on all pulleys.

4. Inspect Wheel Bearings (if applicable)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Grasp the wheel at 12 and 6 o'clock positions and check for play.
3. If there is excessive play, disassemble the hub assembly to inspect and replace the bearings as necessary.
4. Reassemble and torque all bolts to specifications.
