Can't say anything without seeing it, but is your engine idling at too high of an rpm? That can cause dieseling too. It is hard to say on the gear install. There could be a number of things going on (wheel bearing, axle joint, drive shaft, ect). Does it make noise w/out the hubs in? I'd start by taking the drive shaft off and locking the hubs again. See what happens. The drive shaft seems to be a very likely culprit to me.
