Sorry to hijack...my rear is whining, I changed the oil twice in the last 2 years. My indy used 90w I think, was fine until this fall when I noticed some noise when driving with the windows closed. The last time I bought Royal Purple 75-90w with LSD additive. It didn't improve the noise. Would using the 140 decrease the noise or should I start thinking about looking for a new rear end? Bently doesn't specify weight, just has letter designations...I was told by the dealer to use the 90w.

You may need to replace it. I had an e28 that did it for years. I was told the only practical option was to replace with a factory rebuilt or used diff. Typical shops do not generally rebuild.
