Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the 12V battery to prevent any electrical issues during inspection.
Gather necessary tools, including a socket set and torque wrench.

2. Inspect and Replace Motor Mounts

Locate the Motor Mounts: Identify the location of the motor mounts securing the electric motor.
Remove Bolts: Use a socket set to remove the bolts securing the motor mounts to the chassis.
Inspect Mounts: Check the motor mounts for any signs of cracks or excessive wear.
Replace If Necessary: If any mounts are damaged, replace them with new parts.
Reinstall: Torque the new motor mounts to the manufacturer’s specifications (typically around 30-50 Nm depending on the model).

3. Wheel Alignment and Balance

Inspect Tires: Check for uneven wear patterns that could indicate alignment issues.
Balance Tires: Use a tire balancing machine to ensure the wheels are balanced correctly.
Alignment: If necessary, take the vehicle to a professional for a full wheel alignment.

4. Reconnect Battery

Reconnect the 12V battery and ensure all connections are secure.
