Solution

1. Preparation

Tools Required: Jack stands, wheel chocks, lug wrench, socket set, brake cleaner, and safety glasses.
Raise the front or rear of the vehicle using a jack and secure it with jack stands.
Make sure the vehicle is on a flat surface and the parking brake is engaged.

2. Brake Inspection and Replacement

Remove Wheel:
- Use a lug wrench to remove the wheel bolts and take off the wheel.
Inspect Brake Components:
- Check brake pads for wear; replace if less than 3mm thick.
- Examine rotors for grooves or cracks; replace if damaged.
Clean Brake Components:
- Use brake cleaner to remove dust and debris from calipers and rotors.
Replace Brake Pads:
- Remove caliper bolts using a socket set.
- Slide out old pads and install new pads.
- Reattach caliper and torque bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall Wheel:
- Put the wheel back on and torque the lug nuts to specification (typically around 76 ft-lbs).

3. Wheel Bearing Inspection and Replacement

Check for Play:
- Spin the wheel and listen for noise; check for lateral movement by shaking the wheel.
Remove Hub Assembly (if necessary):
- Disconnect brake caliper and rotor.
- Remove wheel hub assembly bolts using a socket set.
Replace Wheel Bearing:
- Press out the old bearing using a bearing puller.
- Install the new bearing using a press and ensure it’s seated properly.
Reassemble Components:
- Reattach the hub assembly and torque to specifications.
- Reinstall brake components and wheel.

4. Drivetrain Inspection and Repair

Visual Inspection:
- Check for any visible damage on axles, CV joints, or differential.
Replace Damaged Components:
- Remove any damaged axles or joints by disconnecting from the differential and wheel hub.
- Install new components and torque according to specifications.
