2020 model X raven clevis mount

[samir786]

Hey everyone,

I have 2020 model X raven. Tesla replaced half shafts with gen2 and the vibration reduced however the car still vibration little bit on accelarating. They didn't reach clevis mount. They told me your model doesn't have Clevis mount but I have doubts. Do you guys know if my model has a clevis mount?

If you look at the actual service bulletin, you will see that on your year (at least on mine that is a 2019), the clevis mount may require repositioning at the time the half shafts are replaced, but the clevis mount does not get replaced.

• Use chassis ears and other methods to narrow down the sound to the front axle.
• Compare the observed sound to the recording in the description.
• Occurs under hard acceleration, typically between 30-50mph
• Gets better with lower suspension settings
• Rule out other possible causes:
• Check if front axle nuts are properly torqued. See Article #29859.
• Confirm ride height is with in specification. See Wheel Alignment
• Inspect the torque reaction arm for torn main bushings.
  • If the bushings are torn, replace them according to Service Manual procedure:
    • Model S: Mount - Front Drive Unit - RH (Remove and Replace) FRT No: 39012402
    • Model X: Mount - Front Drive Unit - RH (Remove and Replace) - FRT No: 39012402

This the latest on halfshaft vibration


High halfshaft CV joint angles can cause internal rollers to not be aligned with tripod housing tracks resulting in sliding instead of rolling. This creates a third order Generated Axial Force (GAF) in the direction of the drive unit (DU). When GAF frequency couples with DU lateral natural frequency, resonance occurs resulting in “shudder”.
The shudder is typically felt through the steering wheel and seat when accelerating between 30-50mph. Under hard acceleration, the vehicle squats, changing the front halfshaft angles to the point where they may create an abnormal shudder under load. This effect is less pronounced at low ride height, and is increasingly noticeable as ride height increases.

The shudder magnitude can be exacerbated by:

• higher running angles (higher ride height)
• drive unit torque output (aggressive acceleration)
• halfshaft tripod housing wear
• lubrication

This article does not describe a wobbling half shaft - see Article #23455 for significant/observable balance issues.
