I hear ya on the seals, but do it right the first time!
Yeah; it must be because you ordered a YJ kit as mine is the TJ shafts only. Mine is an '03 so seals and such are good.
I asked about your kit as i'm overhauling a Comanche right now and I plan on removing the vacuum disconnect and going with the PosiLock cable actuator kit.
You know; Stu and I were talking the other day and I might have goofed. The Warn hub kit comes with Warn outter shafts. The Superiors won't work.
