I carefully studied the topic, began to experiment, in the 50/50 track mode there is no vibration at all. My car vibrates from the start, I really don't like it. Today I have replaced the right shaft 1420113-00-b. For information: the right and left half-shafts on our plaid come from the Model X Raven. The vibration is completely gone. What conclusions can I draw: there is a mechanical problem, a problem with the half-shafts, the shaft gets damaged, after which the plaid starts to vibrate. solution to issue 2, modify the half-shafts, or modify the software by reducing the torque at the software level at those speeds in which there is vibration.
Interesting. Tesla replaced both of my half shafts, but the vibration came back in a few days, with maybe only two hard accelerations, always in low suspension mode. So, I'd guess the half shaft isn't being damaged, but instead perhaps "wearing in" to normal tolerances. Or the grease internally is flinging out of the CV joint and throwing the shaft out of balance?
Yeah, they put the same shafts in mine:
LH(1420113-00-B) and RH(1420119-00-B)
actually, they labeled them differently on my invoice. Did you replace driver's or passenger side?
