Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it on jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Check Brake Pads and Rotors:
- Examine the brake pads for thickness; replace if less than 3mm.
- Inspect the rotors for scoring or warping; replace if necessary.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide off the caliper and support it with a bungee cord to avoid straining the brake line.
- Replace the old pads with new ones, ensuring the backing plate is clean.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-30 ft-lbs).

4. Inspect and Replace Wheel Bearings (if necessary)

Check Wheel Bearing:
- Spin the wheel by hand; listen for grinding or roughness.
Replace Wheel Bearing:
- Remove the axle nut using a socket set.
- Disconnect any components obstructing access to the bearing (e.g., brake caliper, tie rod).
- Press out the old bearing using a bearing puller and install the new bearing.
- Reassemble components, ensuring everything is torqued to specifications.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specifications (usually 76-83 ft-lbs).
Remove the wheel chocks.
