Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel by loosening the lug nuts with a socket wrench.
- Use a torque wrench to remove caliper bolts and take off the brake caliper.
- Remove the brake pads and inspect for wear; replace if less than 3mm thick.
- Inspect the rotor for scoring or warping; replace if necessary.
Replace Brake Pads:
- Clean the caliper and rotor surfaces with brake cleaner.
- Install new brake pads in the caliper bracket.
- Reattach the brake caliper and torque bolts to manufacturer specifications (typically around 25-35 ft-lbs).

3. Inspect and Replace Wheel Bearings

Check Wheel Bearing:
- Remove the wheel from the affected side.
- Inspect the wheel bearing for smooth operation by spinning the hub.
- If there is noise or roughness, remove the hub and replace the bearing.
Replace Wheel Bearing:
- Use a bearing puller to remove the old bearing.
- Press in the new bearing using a hydraulic press.
- Reassemble the wheel and torque the lug nuts to manufacturer specifications (typically around 76-80 ft-lbs).

4. Inspect and Replace CV Joints

Check CV Joints:
- Inspect the outer and inner CV joints for torn boots or play.
- If damaged, remove the axle from the vehicle.
Replace CV Joint:
- Use a CV joint removal tool to separate the joint from the axle.
- Install the new CV joint, ensuring proper lubrication.
- Reassemble the axle back into the vehicle.
