Also might want to limit your down travel with the droop screws. After replacing or straightening the driveshaft. Too much down travel and the drivecup are at an angle that can make them "wobbly". Just a thought 🤔
I'm having a similar issue with mine. Have you figured it out? I opened up the diff case to see if the gears wobble during operation while holding the bears down with my finger. They do wobble and the wobbling is more on one side just like your car. With the diff case open, I could see the gear that comes off of the center drive shaft, or back of the slipper clutch in the rear,and mates with the crown gear on the diffs seems to be wobbling also. This wobbling from the center driveshaft might be causing the wobble in the diff... I noticed that my entire drive shaft has a slight bend also (my car is basically brand new also)and wobble to it also and wondering if a non perfectly straight dog bone shaft, whether its the driveshafts or the center driveshaft, will cause this type of wobbling in general. Maybe the bent dog bones put an uneven force on the drive cups and cause the wobble? What I think could have caused my bent center drive shaft: On the first two runs I had the grub screws that hold my center drive shaft to the drive cups at the front and rear come loose and let go. This caused me to loose front drive both times. It could be that the shaft bent when the loosening grub screw starting pinging off the side of the motor, which is close to the shaft. I have applied blue loctite to the new grub screws I installed. I believe this is a very common problem and recommend doing this right away. It could be that the drive shaft bent when I incorrectly screwed the drive cup onto the center drive shaft in a fashion that caused the shaft to not have enough play between the c cups, and could have bent during flexion of the car. Just a theory but Im gonna just run the car until something wears out at this point. Might be overthinking it and everything is fine lol.
Thanks! I later found that the rear differential was bad with all four screws stripped the wouldn't stay tightened, I purchased new one with the $35 AliExpress refunded for defect on new car.
It’s the dogbone rear axle that’s bent. Get the cvd axles/drive shafts and you’ll be fine. Also get some shims for the diffs. I recently got the wheel extenders and I couldn’t believe how much of a difference they made. COMPLETELY CHANGED THE CAR!
I run the wheel extenders too. I like the look and performance of them. My only complaint is I have to rebuild my rear diffs a lot. The outdrives sheer where the pin goes through the shaft on the inside of the diff. It's a cheap and easy fix but it's annoying. It happened to me about 6 times last summer. I wish they made upgraded outdrives.

It was like this new out the box from AliExpress, they refunded about $35 for new parts

Where do you buy affordable replacements or upgrades?

I'm not sure which extenders would work can you refer me to them? The wheel hole is only 3-4 mm the ones I have are too big
