RUSTLING BEARING NOISE (1 Viewer)

[whitewo7f]

Hi Gents

I have a noise from my 76 series I can describe as a rustling sound from a bearing perhaps.The noise only occurs at high speed over 80km/h under load or me pressing on the accelerator and goes away when released, so I can make it come and go.
My thinks is 3 options

Front Auto locking hubs/bearings
Propeller Shaft / Universal Joints
Rear diff Pinion bearing

Please assist.
Many Thanks
