Solution

1. Preparation

Gather necessary tools and parts for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel covering the brake assembly using a socket set.
2. Inspect the brake pads; if worn below manufacturer specifications (usually 3mm), replace them.
3. Remove caliper bolts and lift the caliper away from the rotor. Support it using a bungee cord to avoid strain on the brake line.
4. Replace brake pads with new ones, ensuring they are oriented correctly.
5. Reinstall the caliper and torque the bolts to the manufacturer’s specifications (typically 20-30 ft-lbs).

3. Replace Serpentine Belt

Sub-steps:
1. Locate the serpentine belt routing diagram (usually found on a sticker under the hood).
2. Use a wrench to relieve tension on the tensioner pulley and remove the old belt.
3. Inspect the belt tensioner for wear; replace if necessary.
4. Install the new serpentine belt according to the routing diagram.
5. Ensure the belt is seated properly on all pulleys.

4. Inspect Wheel Bearings

Sub-steps:
1. Lift the vehicle and remove the wheel.
2. Check for any play in the wheel by gripping it at the top and bottom and shaking.
3. If there is play, remove the hub assembly and replace the wheel bearing.
4. Reassemble the wheel and lower the vehicle.
