Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and securely lifted if necessary.
Disconnect the vehicle's battery for safety.

2. Inspect and Replace Wheel Bearings (if needed)

Remove the Wheel:
- Use a lug wrench to loosen and remove the lug nuts.
- Take off the wheel to access the brake assembly and wheel hub.
Remove the Brake Caliper:
- Use a socket wrench to unbolt the brake caliper from the mounting bracket.
- Carefully hang the caliper using a wire to avoid putting stress on the brake line.
Remove the Brake Rotor:
- If applicable, unbolt and remove the brake rotor to access the wheel bearing.
Remove the Wheel Hub Assembly:
- Unfasten any bolts securing the wheel hub assembly to the steering knuckle.
- Gently pull the hub assembly off to expose the bearings.
Inspect and Replace Bearings:
- Check for signs of damage or wear on the bearings. If damaged, replace them.
- Apply appropriate grease and install new bearings, ensuring they are seated correctly.
Reassemble Components:
- Reattach the wheel hub assembly, brake rotor, and caliper. Ensure all bolts are torqued to the manufacturer's specifications.
- Replace the wheel and lug nuts, tightening them in a star pattern to the correct torque.

3. Inspect Electric Motor and Drive Unit (if needed)

Remove Underbody Panels:
- Use a socket set to remove any underbody panels that obstruct access to the drive unit.
Inspect for Damage:
- Check the electric motor and drive unit for any signs of wear, leaks, or loose connections.
Tighten Connections:
- Ensure all electrical connections and mounts are tight and secure.
Reassemble Panels:
- Reattach any underbody panels removed during inspection.
