Yep. 100% disappears at that point. I tend to think it’s front motor related to some degree. But I also admit I have no idea.

Jebinc’s Plaid Vibration Experiment Results!!!
- Thread starter jebinc
- Start date
By now the only thing I can do is call Tesla sales, identify myself by my reservation number and tell them I am considering the cancelling of my order If I cant find information on the progress Tesla has made on the resolution of this vibration problem. I will ask them for phone numbers of management at Tesla head quarters, tech department, whoever!! I want to know the contact info for the manufacturer of these shafts for Tesla and talk to them too.
Tesla's response to their customers with this issue so far is a disgrace, telling anyone with the problem that this "is normal", "does not effect drivability", does not effect safety"... The one thing they leave out though is, "does effect the customer"..

3/5/22 Update:
Well, dropped off my vibrating plaid at the SC yesterday because of a slew of electrical errors being randomly thrown, a busted for the third time door handle, misaligned headlights, recall items, and….. more D&R of the vibration matter. I was given a P100D as a loaner and the car is expected to be in the shop for days as they troubleshoot the electrical fault. Since the poor loaner seems neglected, I gave it a quick whore’s bath.
They suspect it’s the PCS (Power Conversion System), aka, “the D to D converter” to be at the root of the electrical issues.

I am hoping that vibrations over time are not setting you up for more issues of various sorts later on. I am sure these cars were designed to take road vibrations but can it take the intensity delivered by the shafts?

This may be a new topic: 2022 Model S Front Suspension Damping. The car has the active suspension. At any setting, the car has a vibration "ring" when hitting lane markers at 45 mph. It lasts for about one second, starting strong, then declining....a classic ringing situation. Started at about 1100 miles. Easily repeated. Anyone encountered this?

Haven't felt that. Can you capture it on the suspension graph?

I will have to figure that out. I have no experience using it, but will look today. Is there a primer somewhere?
Please remember this thread is for a specific vibration situation. Thanks for your understanding. Maybe create a new thread for discussing this one of a kind situation? Thanks again.

OK. Will study up a bit, then create a new thread.

Click on suspension, then show more details. It shows a graph of the suspension in real time. You might be able to have a passenger shoot a picture of the graph after it happens.

Need a free minute. I was thinking of doing it today. I noticed the vibration coming back. Less than 100 miles, maybe two hard accelerations.

Well, I think we've figured out it isn't caused by wear or damage to the half shafts. I don't think there's any way I could have damaged a half shaft with the boring driving I've been doing. I must be a design flaw that enables the vibration.

I am convinced that if the outputs of the differential are not held more solid, the orbital movement will cause vibration. CV joints are designed to maintain a constant velocity between halves of the joint to a point, until the angle of the joint is changed. Gradually, with an increase in angle and under power or resistance, the velocities in any joint will separate to the point that the differential, or driver, will be forced to compensate by orbiting around the centerline of rotation. One would be amazed of how little distance from centerline it would take to shake your teeth out. I am thinking that the way everything is mounted in rubber, far above the centerline of output of force, is what allows this movement. These forces will always be present as it is basic physics. At one end of the drive shaft the wheel is well supported and in firm contact with the road. At the other end the output of forces (or input during regeneration), is the motor / differential mounted in rubber. Which end do you think is vibrating? I propose that Tesla needs an additional rubber mount at the very bottom of the differential housing just behind the steering rack. Obviously, this requires a new housing and a place on the frame to mount to.. Lots of redesign and probably why they don't have a "solution".
@lbowroom I raised it to stock and vibration returned. Then I had a series of electrical faults and errors (unrelated). So, I pulled the links and replaced with stock before I dropped it off at the SC on Friday. Prior to raising, it was still good at .5-75” drop.
