Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during inspection.

2. Inspect Tires

Tools Required: Tire pressure gauge, visual inspection tools.
Check the tire pressure and inflate them to the recommended levels.
Inspect the tire tread for uneven wear; replace if necessary.

3. Check Wheel Bearings

Tools Required: Jack and jack stands, socket set.
Lift the vehicle and remove the wheel.
Spin the wheel by hand; listen for any grinding or roughness indicating a bad bearing.
If the bearing is faulty, replace it with a new one.

4. Examine Drivetrain Components

Tools Required: Socket set, torque wrench.
Inspect the electric motor mounts and transmission for any signs of damage or looseness.
Tighten any loose bolts to the manufacturer’s specified torque settings.
