Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Brake Inspection and Replacement (if needed)

Remove the Wheel
- Use a lug wrench to loosen the lug nuts and jack up the vehicle.
- Remove the lug nuts and take off the wheel.
Inspect Brake Pads and Rotors
- Check the brake pads for thickness; if less than 1/8 inch, replace them.
- Inspect the rotors for scoring or warping; replace if damaged.
Clean Braking Components
- Use brake cleaner to remove dust and debris from the brake calipers and rotor.
Install New Brake Pads (if applicable)
- Remove the caliper and old pads.
- Compress the caliper piston using a C-clamp or brake tool.
- Install new pads and reassemble the caliper.

3. Serpentine Belt Inspection and Replacement (if needed)

Check Belt Condition
- Inspect the serpentine belt for cracks, fraying, or signs of wear.
Replace the Belt (if applicable)
- Loosen the tensioner using a socket and ratchet.
- Remove the old belt and install the new one following the routing diagram.
- Reapply tension to the belt using the tensioner.

4. Wheel Bearing Inspection and Replacement (if needed)

Check Wheel Bearing Play
- With the vehicle raised, grab the wheel at 12 and 6 o'clock. If there is movement, the bearing may need replacing.
Replace Wheel Bearing (if applicable)
- Remove the brake caliper and rotor.
- Remove the hub assembly and replace the bearing using a bearing puller.
- Reassemble all components in reverse order and torque to specifications.
