Low Mileage Shutter When Coming to a Stop

[KBoy420]

Hey all,

 

Just picked up a 2016 Sierra 1500 Denali crew cab.  It was a single owner woth 39,500 miles.  Service records are all there and everything has been done according to schedule. 

 

Love the truck alot.  But it randomly will shutter/vibrate when coming to a complete stop.  It doesnt do it while stopping/slowing down, just at the very end of the stop when the truck stops moving.  It sort of feels like drive line slop.  Visual inspection shows nothing.  Everything is super clean underneath and nothing is jumping out at me.

 

Some jad suggested it might be the collission sensor seat vibrating that im feelong but it is definitely something mechanical underneath.  

 

Thanks for any suggestions.
