Update: I'm still waiting for the truck, but after several calls they confirm
@WalleyeMikeIII thoughts. The coolant line needs the front axel and diff to be removed to access the line, after dropping the axel, that's when they noticed the boot is "not allowed to roll out of the dealership" and the axel is on backorder. Sooo fuuu###.
After discussing with the svc Mgr, he arranged for a porter to pickup an axel from a new vehicle on another lot (200 miles north) which is being dropped into my truck. They'll get the backorder axel for the other truck later.
Supposedly I'll get it back tomorrow, I'll keep you posted. Attached is my "busted" axel boot.
