Car Info: 97' Dodge Cummins and an RSTI thingie
Yeah, I'm just worried because I noticed a shudder when starting off in first and on engine braking since I had the gear oil change it done. It felt kinda like when my 98 impreza's clutch was going out, so I was thinking that it might be the clutch. So now I'm wondering if its my rear diff....

All shops make mistakes, you can tell a good shop by how it resolves them.

Subaru Gold Extra is also a rear differential fluid for non clutch type differentials. They are specially formulated from Subaru that meet both GL-5 and hypoid gear requirements.

Code 3 Suby,
I confirmed with both Kevin and Jerry concerning your issue, your car does have the Subaru LSD rear differential fluid, I just didn't note it in your invoice because it is the same price as the Extra S, and I must have forgotten.
If you have any other questions or concerns at all please feel free to come by the shop or give me a call.

Here is my $0.02, even if the wrong non friction modifier fluid or fluid and someone didnt add the modifier...it should and generally wouldn't cause a whine noise, like Kevin said...it would chatter b/c its not smoothly slipping (when in a tight turn).
Not having fluid in the diff could cause a noise/whine. Getting rear diff bushings can cause a whine. was it just fluids you had replaced? if so I would not suspect even the wrong fluid (if that was even the case).
As long as their is "gear oil" of some type in that diff....it wouldnt cause a whine. Only when turned in would the plates make noise. In a straight line, only real reason for a diff to whine would be if there was no oil, lack of oil, and/or parts are worn out (tolerance issues).
again, my $0.02
