i can hear a winding noise for the rear of my cruiser sounds like maybe diff or something starts to become noticeable at around 60kph anyone have any idea's???..does not seem to make any difference when i apply clutch

More than likely the diff. Could be carrier bearings but most likely the pinion bearings. Is there oil leaking from the pinion seal? How long since the diff oils been changed?

i had same problem thought it was my rear diff ..after a rebuild ..noise still there
turned out to be transfer case ...

same problem noise at 60-80 when not on the fuel

just a thought , have you adjusted your handbrake? if so back it off a bit I adjusted mine and it created an awfull vibration I couldnt find ,,,, was truely baffled , backed off the handbrake ,,,,, problem solved

I would definately check your tyres first to see if they have any feathering or scalloping (can sound like a bearing), tyre pressures?, its always good to check easy things first. Hope that helps.
Carrier bearings should change note when power on or off,axle bearings will change note when turn from side to side while driving along so as to apply load to bearings.
