GM says no towing or steady speeds for the first 500mi for ring and pinion break in.  After 500mi, hook up.

That’s funny about what GM says, I flew from New Jersey to Laura  in Missouri to get my 17 Denali  Duramax picked it up and drove 80 miles an hour all the way back to New Jersey only stopping for fuel I hope I didn’t mess it up!
