Does the shudder happen only when you tow or does it happen during regular drives with no tow load ? My MX LR+ is due for delivery in Dec and I have to think twice now.

My own experience in a 2017 X with 50K miles and original half shafts is that when towing my 2,300 lb travel trailer the shudder is more noticeable compared to when not towing, though in both uses cases I have to accelerate pretty briskly for it to be detectable.Does the shudder happen only when you tow or does it happen during regular drives with no tow load ?
It happens without a load as well, but not as noticeably, because I keep the suspension in low. When in standard height, it's quite bad in the same speed ranges.Does the shudder happen only when you tow or does it happen during regular drives with no tow load ?

This is interesting, since the speed range is effectively the same as mine.My shudder is only noticeable between about 34-38mph and has been unchanged for tens of thousands of miles.
Based on what I’ve read on TMC speeds in the mid-30’s are where the shudder typically appears. Your post mentioning a 53-58mph range is the first time I’ve seen that mentioned, as near as I can remember.This is interesting, since the speed range is effectively the same as mine.

How many miles have you driven on it post half shaft replacements?I have a 2020 Model X, build March 10. I had the shudder problem from day one. I also had both front drive-shafts replaced. The car is perfect now!
I've got a 2020 MX LR w/ 22" wheels that has developed a case of the shudders on acceleration. I was going to post on here about it and found this long thread going so I see it's not unique to me. And we are not talking fast acceleration, just moderate to pull into traffic. Time to make a service appointment.

FWIW, there’s a group on FB devoted to this problem and a legal firm has joined the group and is looking for members (presumably to join the class).i had exactly these symptoms at these speed ranges in my Sep 2019 MX LR. Started developing at about 3,000 miles driven. The first 12,000 miles or so I was towing for between 9,000 and 10,000 of those miles.
Tesla service replaced front axles (nov 2019) and problem was gone for a few thousand miles.
replaced again (feb 2020) and fixed until recently. problem is now resurfacing (39,000 miles). Haven’t towed since dec 2019.
now operating vehicle on “low” suspension mode and shudder is only present under moderate or hard acceleration. Very noticeable even under mild acceleration with “standard” suspension height. Which means I can’t tow, which is the reason I sold my S and bought the X.
Tesla claiming there is no solution is simply Tesla stating they are unwilling to solve the problem. I sure hope a class action lawsuit isn’t needed to get the company to do the right thing and find a fix and retrofit it.
This is very, very disappointing.
Please post your date of manufacture (it's on your VIN sticker at the front door area).
And how it's resolved.
Thx.

Interesting enough, the local SC does not have the new part numbers in their system and cannot order them nor are they aware of a fix..I gather that your local SC is misinformed?
Others here have reported success with the latest half-shaft replacements (new source for Tesla?) and that the repairs seem to now last.
Why not just forward the new part numbers to your local SC and ask them why they don't know about them, and that you'd like them installed ASAP?
Yeah, I heard this same thing. I translated it as "this should hold him off for a while."They looked and confirmed both problems but stated that engineering is working on part revisions and recommend against replacing with existing parts now.
