2020 GLS 450 Front Axel Issue
2020 GLS 450 started making a thumping noise (not cracking or popping) from the driver side front axel when making sharp turns at slow speeds. Took it to the dealer a few weeks ago and they determined the axel shaft needed to be replaced. After installing the new axel shaft, the problem was not solved. They are now thinking it’s the from differential. Service advisor said it could be a month or so before the parts come in.
Has anyone had any similar issues? If so, what was the fix?
Vehicle currently has 48.5k miles. Service advisor said they would keep the ticket open until the issue is resolved being that I’m so close to being out of warranty.

They're just firing the parts cannon. If they're covering it under warranty I wouldn't worry about it. They'll eventually get it right. Little you can do about it.

Yup, this is correct. The dealership don't know what is the real cause and they are just throwing whatever and see what sticks (fixes the issue).

One interesting note: everything was covered under warranty, but since replacing the front diff didn’t fix the problem, they took the new part off and replaced it with the old one. I thought that was interesting.

I do want to mention that the service writer gives regular updates on where my vehicle is in the process so no complaints there.
