Solution

1. Preparation

Gather necessary tools and parts for the inspection and repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery before starting work on electrical components.

2. Inspect and Diagnose Drivetrain Components

Tools Required: Floor jack, jack stands, socket set, torque wrench.
Raise the vehicle using a floor jack and secure it with jack stands.
Inspect the drive shafts and axles for any visible damage or excessive play.
Check the differential fluid level and condition; replace if necessary.
Reconnect the battery after inspection.

3. Test Electric Motors

Tools Required: Tesla diagnostic tool, multimeter.
Use the Tesla diagnostic tool to run a performance test on the electric motors.
Measure voltage and current to ensure they are within specifications.
If motors exhibit irregularities, consider replacing them.

4. Repair or Replace Components

If any damaged components are found (e.g., axles, bearings, or motors), order replacements.
Replace faulty components following manufacturer specifications.
Torque all bolts to the manufacturer’s specifications upon reassembly.
