Use Transfer Pump To Change Diff. Fluid?
Here's a quick question: If I don't want to remove the cover from the differential is it possible to use a hand-operated transfer pump to do the job? I see that these pumps are available at auto parts stores. I realize this method wouldn't be as thorough as actually removing the cover but I would prefer to change the fluid this way. Any thoughts? Thanks...

MMMmmmm.... Grits!!
Alot of techs these days do that exact thing, especially on axles that use RTV as a sealant. In your case, you have reusable gaskets, so I'd still pull the covers to do the job right.

Thanks, guys. I think I will have the cover removed after all. I'll have the dealer order a gasket since I feel more comfortable with one just in case. However, the original gasket should be good to go, is that not correct? Thanks again...
Oh, another quick question. I'd like to wait a while before doing the front differential (truck has a little more than 26k on it, towing occasionally). Am I right in assuming that the rear differential gets hotter because it is the one that is propelling the vehicle when not in 4WD and the front diff is just "coasting"?

That is correct, however the hubs are always engaged. So just like a transfer case that is never put into four wheel drive, it is always spinning with some load. Use your best judgement, and don't be suprised when the old fluid comes out looking almost new. I wait till 40k on my trucks since 03 and it has always looked about the same as what went back in.
