Thanks for the follow up, Oyinko. Were any of the other suggestions on Reddit useful? I see some people talking about re torquing the lug nuts and axle shaft nut. Others talk about half shaft spline tolerance and missing spacers. Its unclear how much those have to do with the problem.

I don't know. The first thing Tesla did when I reported the issue was to retorq front drive unit, assembly and control arms but it did not solve the issue. I'm not sure what is "half shaft spline tolerance and missing spacers".
A half shaft is the CV axle that connects the wheel hub to the drive motor. If the splines on those are not of tight enough tolerance, you can have slop between moving components. Another Tesla owner commented on this being a potential problem but I didn't see a confirmed solution. Another said the service department found that a spacer (probably a washer) was missing from the hub assembly from their model S, and that once replaced, the clicking noise they had went away.
Thanks Oyinko. They are encapsulated by the hub when assembled, so it would not be possible to see them without disassembly. But for reference here is a photo of a Tesla front drive half shaft (this one is for a Model S)

On the right hand side you can see the axle nut, and just to the left of the nut are splines.

Just made 3 new videos. If it would be gear lash, shouldn't get the noise also going backward?
Front Left Wheel going forward = noise
Front Left Wheel going backward = no noise
Front right wheel going forward = noise but much more subtle.

"Replace Front LH And RH Stabilizer Bar Links Due To Ball Joint Cracking"
My brother had a low speed clunk noise also and this is what they did. Mine is recalled also but they said safe to drive. Our units are rwd though. He only could hear clunk noises if opened window.

I called service center and my vin 41xx was on the recall list for ball joint links and a battery breather. No notifications via email or regular mail. My brothers vin 65xx. He complained about the clunk and also updates failing. They said to bring in and they replaced links.

Nope
But when model x was in for yellow line on screen replacement, they ran my model 3 vin and mine was on list. I don’t think it’s an official recall. Mine doesn’t seem to clunk so I’ll get parts replaced when 3 goes in for something else.

Sandie, thanks for sharing.
Can you ask your brother to watch Oyinko's video to see if the sound is identical to what he heard?

This is gear lash. Not only that, it's so subtle that I almost can't believe it's a complaint. The motor is louder than the gears meshing, but the concern seems to be about the nose when you roll backward while in D and then apply torque again. I'm not sure I understand what the worry is about, honestly.
Have you seen my last video? It's definitely not subtle on my car. Tesla already replaced my front drive unit because considered the gear lash and noise that came with it was out of specs.
I'm rolling backward in the video because that's the only way I can replicate it easily. I don't get that noise every time I accelerate when I drive normally but it's happening often enough and loud enough that it's bothering me a bit.
Its hard to say without getting in there to see what is being loaded and unloaded when the noise occurs.
I went back to the showroom where I originally drove a P3D and test drove two of them. The P3D I originally drove did not make the clicking noise. I tested it similar to the car I ordered and the comparison at the service center (flat ground). That car had about 800 miles on the clock. When I drove the second P3D, I initially didn’t hear the noise. But, I then tested it on an incline and it made the clicking noise. Something I also noticed is that the noise was hard to replicate when creep mode was turned on. When I turned off creep, the noise was easier to replicate. That car had 1,500 miles.

Is your Model 3 AWD or Performance making a similar sound?
According to the SC, it's coming from the gear backlash and is supposed to this sound but I'm a bit skeptical
To reproduce the sound, put the car on a hill. Stop the car and press the accelerator pedal a bit to accelerate from 0 to 3mph in a short bursts, several times. You should hear the clunk sound that I describe.
Any news from anyone on this? My P3D was in for other things and I mentioned the clunking noise that I too am experiencing. Service details simply says they reported to engineering. Did not have the possibility to enquire with the advisor as I picked it up after service hours.
