Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the high voltage battery (if applicable) to ensure safety.
Tools Required:
- Torque wrench
- Socket set
- OBD-II scanner
- Multimeter
- Floor jack and jack stands

2. Inspect and Replace Tires

Check tire pressure and adjust to recommended levels.
Inspect tires for uneven wear and replace if necessary.
- Use a tread depth gauge to measure tread wear.
- If replacing, ensure to balance the new tires properly.

3. Address Drive Unit Fluid Issues

Check the drive unit fluid level:
- Remove the fill plug on the drive unit.
- If the fluid is low, add the recommended Tesla gear oil until it reaches the appropriate level.
Inspect for any leaks and replace seals or gaskets as necessary.

4. Inspect Drive Axles and Suspension

Remove the front and/or rear wheels to access drive axles.
Inspect axles for signs of wear, such as torn boots or excessive play.
Replace any damaged axles or CV joints.
Reassemble and tighten axle nuts to the manufacturer’s torque specifications.

5. Test Drive and Monitor

Reconnect the battery and take the vehicle for a test drive.
Monitor for any shuddering or vibrations during low-speed acceleration.
If issues persist, further diagnostics may be required on the drive unit itself.
