Grinding sound from front diff while turning?

Question

Hello, I have a 21 max with under 500 miles. I was wondering if any of y’all have the annoying grinding sound as well? Mine only does this while turning at full lock left and right. Will this get better as the machine get used more? Could the front diff gears be bad? 
 
Dealer said it was normal???

I asked the dealer about this. They told me that there is a shim pack from brp. It is covered under the factory warranty. These shims go inside the front diff. It really hasn’t got any worse yet, so I’m not sure what to do? Will this be only a band aid? Maybe I will see if it gets louder. I’ll let y’all know

I was having grinding sounds coming out of the front diff and someone recommended changing the front diff oil and inspecting it. I found that my oil level was low and it was a bit dense with metal. After it was full the sound was gone. It is a easy enough thing to do.

Since you're getting this while steering hard, that is when the diff "slips" so the outside tire can spin more than the inside. At least that is my understanding...

Can’t answer this question, but can relate to the issue. We had an issue 1 month after purchasing a hd8, dealer replaced front diff. This was at 30 hours on the machine. Cuirntly sitting at 60 hours and the grinding started again. Do you have an update or any resolution?

We have this problem with our 2022 Defender HD9.   The dealers we've called to schedule repairs claim they have NO info on a bulletin re: this grinding.     Could you please post a copy of that bulletin your dealer printed for you on this forum?   I know it would help us to get our issue fixed this year since we don't want to do additional damage!    Thanks.

So I had my dealer install a shim kit into the front diff. I now have almost 1200 miles on my machine. So far so good. No weird noises or grinding. The dealer told me that brp has known about the issue
