Stop in for a cup of coffee

Morning!
Just below freezing and not snowing.Yet.
Son found a used rear diff for his chevy,needed Avalanche to pick it up. Warned him about latching the tonneau properly. Thats twice he has demolished a rear diff in that truck. I say hes hard on it,he’s blaming the 35’s. I let it go, but i know abuse when i see it. The clockwork in the chevy diffs are robust, and fragile. Abuse em and thats what happens.
