Solution

1. Preparation

Gather tools: jack, jack stands, socket set, wrench set, brake cleaner, and a torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Brake Inspection and Repair

Remove the Wheel:
- Loosen lug nuts slightly.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Components:
- Check the brake pads for wear; replace if they are less than 3mm thick.
- Inspect the brake rotors for scoring or warping; replace if necessary.
- Clean the brake components with brake cleaner.
Replace Brake Pads/Rotors (if needed):
- If replacing pads, remove the caliper bolts and slide the caliper off.
- Replace old pads with new ones, ensuring proper orientation.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 25-30 ft-lbs).
- If replacing rotors, remove the caliper bracket, then the rotor, and install the new rotor.

3. Wheel Bearing Inspection and Repair

Check Wheel Bearings:
- With the wheel removed, grasp the rotor and wiggle it side to side; any play indicates a bad wheel bearing.
Replace Wheel Bearing (if needed):
- Remove the caliper and bracket (as described in previous steps).
- Remove the hub assembly to access the bearings.
- Replace the bearing with a new one, ensuring to pack it with appropriate grease.
- Reassemble the hub and torque all bolts to manufacturer specifications.

4. Suspension Inspection and Repair

Inspect Suspension Components:
- Look for worn bushings, struts, or control arms.
- Replace any damaged or worn components following manufacturer guidelines.
