Forums, internet, don't you love it...

Guy writes in, has no idea what he it looking at (no offense)asks for advice and then the poor advice stream begins, changing a pinion seal without at least some know how is asking for a repeat of the leak at best, killing good operating set of gears or complete lock up and flying into a ditch (or on coming traffic with a schoolbus full of kids) at worst.

Take it to a shop, get it done correctly.

NOT a jiffy lube or other gas station idiot, but rather a shop that knows that axle assy inside and out.

80CJ at least is asking for more info.

The crush sleeve is not right behind the seal, rather between the inner and out bearings. Getting that nut off with hand tools can be done, but getting it apart is not even close to as important as getting back together correctly.
