Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to ensure electrical safety.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors
- Remove the wheel by loosening the lug nuts and lifting the vehicle with a jack.
- Use a torque wrench to remove the caliper bolts and take off the caliper.
- Check the thickness of the brake pads and the surface of the rotors for grooves or warping.
Replace Worn Brake Pads or Rotors
- If pads are worn below the manufacturer's specification (usually 3mm), replace them.
- If rotors are warped or worn, replace them following the manufacturer's specifications.
- Reinstall the caliper and wheel, ensuring all bolts are torqued to specification (typically 80-100 ft-lbs).

3. Inspect and Replace Wheel Bearings

Check Wheel Bearings
- With the wheel removed, spin the hub to listen for grinding noises.
- If noise is present, remove the hub assembly.
Replace Wheel Bearings
- Use a bearing puller to remove the old bearings.
- Clean the bearing housing and install new bearings with proper lubrication.
- Reassemble the wheel hub and torque all fasteners to manufacturer specifications.

4. Inspect and Replace Drivetrain Components

Check CV Joints and Axles
- Inspect the CV boots for tears or leaks.
- If the CV joint is damaged, remove the axle nut and detach the axle from the transmission housing.
- Replace the axle with a new one, ensuring it is seated properly.
