The pump looks sooo pretty... From what I remember reading, before I go and install it, I guess it would be wise to be some of that blue gasket sealant, just to be sure? So the closer I get to getting my truck wheels to turn, the more I'm going over the what else to do list. With that new rear end in there, I remember my buddy welding the perches on and seeing smoke rise from the vent tube on the axle. I'm thinking, that oil probably got a lot hotter than it ever should have, (under normal driving conditions) so it probably ought to be changed out. So I need some advice. Do I just remove the bottom bolt, drain the fluid and refill it, or do I take the cover off the differential and replace the gasket while I'm at it? (Just in case the heat got to the gasket as well and maybe took away some of it's longevity.) Thanks!
