To confirm, I believe the consensus is the seals should be replaced any time the axles are removed? Is that right, or would visibly intact seals be reusable?

To confirm one more point, the stock LS3 Trans Flange isn't usable with the stock ZL1 diff, right?

And I've had to re-read this thread a bunch of times but I don't recall seeing trans or diff fluids. Any recommendations on these?

Thanks again!
For what it's worth...I did not replace the seals on my used ZL1 diff when I put it in. I inspected them...they looked good...in went the axles. Zero leaks. All is well. So in some ways, I think the whole axle seal discussion is being overthought a bit. Have a look at it, it's a rubber seal like so many we've seen before. Holds in the thick diff fluid...not designed to be a submarine driveshaft seal holding 25000 psi at the bottom of the abyss. Make a good logical mechanic determination on it and move on. Some will/should need to be replaced. Others will likely be just fine.

At the end of the day...it's always good to replace a seal I guess. Just do it right. But don't overthink it either.
