So is it the wheel bearing issue? I alway though it is the bearing from front drive unit?

What is this high pitched cricket like noise?

The actual drive unit replacement only takes a day at most. The bigger delay will be how long the part takes to arrive.
initially expected it to be a wheel bearing issue but ended up identifying as motor issue.. can provide more info after I receive invoice

I'm not sure the noises you were hearing are the same as we're describing on this thread.
The high pitch noise we're talking about here sounds like crickets or high pitch static coming that comes and goes:
The high pitch whine you're describing sounds more like just standard inverter whine:
What did the slight loose bearing noise sound like? That seems like a different noise/issue altogether.

It sounds like he had both noises, and that the bearing noise is gone after the motor replacement, but he still hears the (normal) inverter whine.
To me, the noise I hear sounds like very faint but clearly audible coil whine that I might experience from a computer. The inverter whine isn't as high pitched or as intermittent. I've found this sound to be most prevalent from 50-70 with very light throttle application. I personally do not believe it's a bearing.
Hi All
I am having the same issue with my MYLR that I got in Feb 2023. I just dropped it off at the service center yesterday in Fremont, CA and did the drive with the tech. The tech dismissed the issue as the sound being "normal".
After finding this thread I sent a message linking this thread to the service center noting the fix by replacing the front motor because of a faulty bearing. I haven't gotten a response yet.... we shall see.
Has anyone here had success with resolving the issue at the Fremont Service Center in CA? It would be great to find documentation that this issue CAN be fixed and that it is NOT normal.
Thanks!

I had my appointment with the local SC here this week. I was able to demonstrate to the technician that did a ride along with me that the sound was there and that he was able to hear what I was talking about. I left the car there and it sat overnight until someone could look at it the next day. I'm guessing a different tech drove the car the day after, but that tech said he wasn't able to hear anything outside of the norm. Quite disappointing.
I wouldn't say that the noise is loud by any means, but the fact that it's always there at highway speeds, comes in and out at highway speeds, and has that high-pitch annoying ring to it makes it very distracting. I find myself turning the radio up while driving to try and drown it out, but this isn't something that I should have to do.
I made my feelings known to the SC. They said that I could certainly schedule another appointment and they would take another look. It's just frustrating to have wasted those two days without my vehicle for nothing.
You'd think by now that Tesla would know that this is a known issue and have a consistent stance on what to do with it. Right now, it seems like it's all over the place where some SC are working with the customer to fix the problem where others are claiming that it's a non-issue or that it's within normal operating parameters. On all the other Teslas that I've driven during test drives or as part of a loaner system, I didn't have any of this high-pitched whining noise with any of them. It's pretty frustrating for those of us that haven't gotten anywhere yet.

I took my car - LR Nov 2022- to the SC a few weeks ago.
Printed out as much material from this thread as possible, and gave it to the technician.
He confirmed the FDU was the problem after some tests, and ordered a new one.
I heard the noise again a few minutes after picking up the car with the new drive unit. Apparently, another technician actually changed the unit and went for a drive afterwards, and probably didn't hear the sound as he was not familiar with it.
Anyway, I have another appointment in a few weeks.
It is very alarming, that even if one is able to convince the SC to actually do something, the expected fix (replacing the FDU) doesn't work..
I don't know if they are using old drive units, which passes quality control and makes it into the supply chain again?
I will most likely keep pushing for a new drive unit, and make sure he knows not to order a REN part.
My biggest fear is, that they will claim they cannot fix the issue and that it is not a big enough problem to replace my car.
I will keep you posted on this.

I got my 3 in March 22’. Went to the service center 3 times. One time they didn’t hear anything, another they realigned panels and said it was fixed, and the last one they replaced the windshield for free, which had a chip in it so I can’t complain. Time to make another appointment before it gets warm out
I have my SC appt in the morning, so I finally took the chance to read this thread from beginning to end.Quoting from your other post.
Oh wow you're very uniquely qualified to diagnose this!
Not sure how much backstory you're read on this thread but Tesla has a service article for it and they told at least one person when they replaced their front drive unit that it was a bad bearing. It's definitely coming from the front drive unit, but I'm less sure they know it's a bad bearing. I've also thought it sounds like high pressure coolant or maybe even electronics noise, but I noticed mine shuts up when you go around an exit ramp at speed, maybe the loading on the drive shaft/bearings are enough to quiet it. I wouldn't think electronics noise would care about that.
I have a microphone attached to a magnet and took some recordings of the front drive unit and the noise is extremely loud (clips the microphone). Lots of other interesting noises too:
What is this high pitched cricket like noise?
I hear the high pitch sound/cricket sound often. Sometimes the car is quiet as a mouse and other times even at 5mph, I can hear that noise. I hear it often when I am going 50-70mph. Sometimes I do not hear but have been turning up the volume to drown it out. It is annoying that I know it is...teslamotorsclub.com
I also recorded a brief video of the noise I'm dealing with. The audio quality is not great (just an iPhone resting on the console lid), but it's what I had time for today on the way home. There's a certain in-car experience that is difficult to capture via audio recording.
The issue is noticeable from around 0:45-1:10
Same for me. I brought my MY into service on Sunday and test drove with the tech who said he heard it! Now it is has been in the shop for 3 days and now they are saying they do not hear it. I do not understand the purpose of having a tech do a test drive with you to confirm the noise, why are they now saying they do not hear it. This is so frustrating. I even printed out others who have had their front drive unit replaced and still they are not doing anything. I will continue to bring it back to them until it is fixed but I feel that now the weather is getting warmer that the sound may not happen. You can hear it more when it is cold outside. This is really unfortunate and not a great experience.
Lucky you, I had 2 techs confirm at separate times and now they say that they cannot confirm the noise again. Why bother having a tech go for ride if and confirm the noise if they are not going to do anything about it.

That was almost my exact experience. I did a ride along with a tech who was able to hear the problem first hand. I left the car there for them to diagnose further and received the car back the following evening with comments in the notes that they couldn't replicate the sound (I have no idea how because it is there for me 100% of the time).
It's very frustrating and annoying. I don't want to keep wasting my time dropping my car off only to have them say they can't replicate the sound. I don't understand why they just don't have the tech that will be working on the vehicle be the same person doing the ride along so I can show them first hand what my concern is and so they know exactly what to listen for when they're doing their own test drive of the vehicle.
I get it and is not sure how far the SC is from where you live but I want this fixed. Like you, I test drove the car and there was no whining noise at all and if there was, I doubt anyone would have put a deposit on the Tesla. It bothers me a lot that you show them and they can hear there is an issue but days later they do not hear and you get the car back.
Did you ever receive the internal bulletin or instructions or the invoice that I can share with my SC?
