Alright i just put a new axle in my truck with a detriot in it. When i am driving now and im off the gas i feel a slight vibration throughout the floor of the truck. My ujoints are all new, my driveshaft angles are perfect and dead on so i dont think it could be that. The noise tends to come more when im going straight down the road right after i let off the gas. Anyone have an idea what could cause this or is it just how the detriot tends to work?
