    Good morning all, I got my truck back together after the re-gear, all went smooth. Leak free for 250 miles, then this morning noticed my passenger front inner axle seal leaking? Ugh, the shop installed them, but I didn’t get a measurement before I took my diffs to them, does anyone know how far you drive in the seal? Thanks!

    Great info! Zuk has my diffs right now, and I will be installing(again) new seals once I get the 3rd member and clamshell back.

    Also have to do rear axle seals and o-rings.

    that’s what I thought, so I confirmed with him. I might just try both and see which one doesn’t leak haha
