Noise from the rear axle...?

[lotide]

In my 77 Eclat Ive got some noise from the rear axle. Its a deep, continuos noise, from the centre of the rear car, but not from the exhaust. Possibly the differential (there is oil inside)? Someone told me, that the salisbury-diff is always a bit nosy, but my noise seems to be a bit too loud for that. I sense it best on the motorway around a 120km/h, when I lift a little the accelerator pedal. Or could it be some of the joints on the propeller or drive shafts? I greased them all every 5000kms. Does anybody have an advice? Thanks Matt.

Hi,

Sounds like diff bearings have worn to me!
