Hello. I am a new guy from Wyoming. I have a 2005 3500 dually with the 6 speed manual. A wheel seal just went out on the back right diff, so I thought I would try and find the plate on it. The only numbers I can find are 52104 and 528A1. I guess there is several fluids that go into these differentials and I need to know the right one before I pull the wheel seal off, or at least fill it up more until I get the tools necessary to pull the seal out.
