Loud bang from the rear while turning

[brokensendhelp]

The other wheel was on the ground.

Should I try to replace the axel which is arriving next week or should I just leave it be and get it to Tesla to not tinker with anything myself?

I would take it to Tesla.

I'd take it to them first. Pretty sure pulling the axel will dump all the gear oil.

Assuming it wasn't the outer CV being funky, and the inner is fairly straight, any variation in turning resistance after you removed the inital slop is differential damage.

Thanks so much for the help. I'm forever grateful <3

Will take it to the nearest SC (looong way) asap and report back.

For future reference:
- This also happens while turning in Neutral
- This does not happen while standing still
- On some rare occasions you can also experience this while accelerating. Usually very hard.

Good luck!
Be gentle on the drive, kid's car was making noise and the diff failed completely when I turned while accelerating. Tesla's design is different, so it would not fail the same way, but don't push it.

Alrighty, so, I don't know if this is normal?

When turning the wheel, it looks like the wheel bearing, cv joint and axle turns perfectly with the wheel. However, when you get to the second boot (rubber protection towards the DU) it gets a little iffy. It seems to me like there is some play there. Like I can turn the wheel and it takes a little bit more turning before the DU turns. Like there is a delay/play when turning the axle.

Please see my video for a better understanding.

Ouch!, As others said and what you said most defiantly take it to Tesla Service Center. Still under warranty and looks like you will most likely be getting a new Drive Unit. Hopefully the wait is not long for delivery. I had to have my front Drive unit swapped and it was about 2 month wait. good luck and please keep us updated on the result as it will help others in the future that may incur a similar issue.

Thanks! It's a long drive so I'll get it there on a flatbed to avoid a breakdown.

Praying I can have it fixed pretty quickly. There shouldn't really be a wait. Just hoping they have the parts in stock.

Update on this almost a month later.

"Performed replacement of Drive unit.
During service, there was found play in RH tie end rod, lower aft links front and both stab bar links rear. Because of this,
four wheel alignment cannot be performed until replaced."

Getting those parts replaced as well. Picking up the car early August.
