this was a long read... n pardon my long post
unfortunately my X has the shudder, still has original 102711(1/5)-00-B axles..
my understanding is that there's still no real fix? even the newest axles shudder for some ppl
Has anyone taken apart old vs new axles to see the design changes? they all look the same on the outside...
I seriously wonder if they just changing numbers for marketing purposes to make customers feel better or maybe just grease change lol
where u don't want play is in rotational axis between joints n shaft
Also, i think Tesla didn't actually engineered anything n just took already good axle design found in many cars n used it in theirs but didn't account for high angles...
I despise companies like N2itive that chargers ~$400 for $20 dollar part... Those lowering links are not magic or made of gold lol
My bet is on the tripod joint.
I also don't get why not use dual CV joint, that would allow for steeper angle on both sides

Correction, he got the side wrong, tripod/Y joint is by the drive unit.
Not sure what u meant but the way u worded is wrong... Half shaft move left/right by design, along the splines n tripod joint.The issue is the half shafts moving left/right as they develop play in them due to wear.

i personally can't stand these kind of videos, 40min of talking lol. This could be covered in 5min with nice visual aid of actual car componentsPretty good technical explanation of tire wear and shudder problems. fast forward to ~22 minute mark for shudder discussion
I think just not enough cars come back for this so its not worth it for them..Here’s the thing that’s baffling to me. Tesla obviously knows about this design flaw, it’s been around for years and they continue to make warranty repairs to deal with the recurring problem. N2itive, an aftermarket company, has a solution, or at least a mitigation, which lowers the car to prevent half-shaft destruction, in combination with adjustable camber and toe arms to prevent premature rear tire wear due to riding lower.
Tesla is obviously aware of this fix. So, why have they not simply engineered a Tesla solution to the problem? I can’t imagine why, unless by offering a fix they set themselves up for a massive fleet-wide upgrade. But, even if that’s the case, you’d think Tesla would care about fixing a design flaw for their customers, rather than just perpetuating the problem with every new car sold.

I'd love to see one taken apart from the car with shudder issue...Yeah they call it an NVH issue. The noise comes from spalling on the raceway inside the Rzeppa style CV joint, so when the balls travel over the damaged area at high speeds it vibrates the entire thing creating noise and when bad enough shaking.
My bet is on the tripod joint.
Agree. Has anyone taken one apart to see any visible damage?I think the source of the trouble is the tripod joint near the gearbox. GKN has a solution for SUVs with higher angles with 2 more or less normal cv-joints and a ball spline for axial movements.
Why are Volvo using this solution for their bigger SUVs if the tripod could work? The cost is somewhat higher so I think they come to the conclusion that the tripod solution could not work!
I also don't get why not use dual CV joint, that would allow for steeper angle on both sides
What do u call an EV blocking chargers?For example, I couldn’t do this without it …. (Current situation!)
