Whining noise from differential on 88 Silverado.

    Hello, Can anybody tell me what might be causing the whining sound coming from the differential when I am driving. When I take my foot off the accelerator, there is a kind of slight rattling noise also. At first, I thought it might be coming from somewhere in the transmission, but I have the box off for other work, and I am certain it is originating in the differential. Any ideas? Thanks in advance.
