To try to duplicate, the dealership service rep put some amount of weight in the bed...he didn't sense any issue...tried to tell me, 'there's nothing wrong'....I didn't accept that
Once he hooked up to a trailer similar in weight to ours, the problem surfaced....now they've replaced the driveshaft
The point: it's important that, if a problem only occurs under certain conditions, that we insist the repair tech duplicate those conditions in testing
Good point and glad the dealer agreed to hook up another trailer to duplicate your trucks drive line shudder. Not many dealers will do that.
Just weight alone in the trucks bed may not cause a shudder issue....but add several thousand pound trailer plus weight in the bed created your trucks shudder.....especially under hard acceleration getting the combo moving.
