Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Secure Components

Tools Required: Socket set, torque wrench
Sub-steps:
1. Inspect motor mounts for wear; replace if cracked or damaged.
2. Tighten any loose bolts on the electric motor and drivetrain components according to the manufacturer’s torque specifications.

3. Fluid Check and Replacement

Tools Required: Fluid pump, container for old fluid
Sub-steps:
1. Locate the transmission fluid dipstick or fill port.
2. Check the fluid level; if low, add the recommended type of fluid as specified in the owner’s manual.
3. If the fluid appears dirty or contaminated, drain and replace it with new fluid.

4. Tire Inspection

Tools Required: Tire pressure gauge, jack, tire iron
Sub-steps:
1. Check tire pressure and adjust to the recommended levels.
2. Inspect tires for uneven wear; replace if necessary.
3. Rotate tires if uneven wear is detected to balance the load.
