yes the service rep at the dealer recommend I take it to a shop as they "don't repair but replace whole assembly new". The rear brakes I never messed with I have drilled and slotted on the front. I will go out in a min and test the brakes. I had it towed back from the dealer to my house on a non flat bed so if the front diff was bad its F*c***ed now lol. Dealer said they drained all my diff fluid when they looked at it and since i didnt get anything fixed they didnt replace the oil. I had to move the truck 1 time for a school bus and it clunked heavily moving 2mph 10ft.
