Welcome to Chevy Arnie.
Please decribe the details of what your truck is doing. Lots of help available here when we get a detailed story. I just had a front wheel hub assembly fail on our '20 Tahoe under 50k miles. I agree that's low miles for a diff failure.

 

Any updates on this one?

 

Your description does not provide enough info to offer any suggestion.

At this time we don't know if it gear related. brake application related Or anything else.
So as you can see we need to be as specific with the description as possible Thanks.

This is the quote I was wondering about. I understand your notes. Thanks

 

no way to know without inspection. this is not a common issue. Usually its abuse or water filled fluid or bad rebuild that is the cause.
