JY rear axle going in tomorrow... any seals I should replace while it's convenient?

Before I swap in a JY C8.25 rear, are there any axle/pinion seals that could be reeeeeally easily replaced while the axle is on my workbench? I'm picking up the axle tomorrow and I'd hate to miss the chance to do things the easy way.:greensmok

You can replace the pinion seal pretty easily. All you have to do is mark both the pinion and the nut in one spot, like in a line. Then back off the pinion nut, take off the washer, the yoke and replace the seal and reassemble and line up those lines that you made in the first place.
