Minor Vibration

[falcon350]

Hi there, I have an 06 F350 superduty crewcab dually 4x4 6.0 auto, I feel a slight vibration when I let off the accelerater kind of just before it coasts with no load, There's no vibration under load, I'm thinking maybe the centre bearing on the rear driveshaft, any thoughts, Thanks

start by checking your driveline angles and checking slop/play in the carrier bearing. Also check u joints for play/binding.

Thanks for the reply, Will be checking a few things when I can get it on the hoist.

you want to check driveling angles when it's sitting on the ground. If you get real technical in Neutral, with the P brake on and a chalked wheel. that takes the bind off the shaft so you get more true readings and can rotate it by moving the truck slightly to fit your angle tool.
