    not sure why you're using a special tool to install seals, i know they have them...but a piece of 2x4 does the trick, never had one leak yet installing it that way...maybe because the wood gives more than a metal installer?

    Be sure the vent tube on the axle isn't stopped up. If it is, pressure will build up inside the housing and diff and instead of the pressure being relieved through the vent tube, it finds the path of least resistance (in this case the axle seals) and leaks gear dope in the process. Hope this cures your problem.

    I think the 1st set i had on my 14FF did that too, but so far.. knock on wood, the 2nd set hasn't! /forums/images/graemlins/ignore.gif
    In doing the homework on it, i think someone mentioned that there's a super-thin sleeve that can be used to enlarge the axle flange surface just over the size of a gnat's a$$. That little bit makes the seals work mucho-better and no more problems. /forums/images/graemlins/thumb.gif
    Can't recall who mentioned that, but also think they were a tad pricey as well. Maybe it was the K30 guy? /forums/images/graemlins/confused.gif

    I miss my memory! Should you happen to see it, please send it back! I'd give a description, but i can't remember!!

    The C/R brand sleeve for a 14 bolt is #99282, I got mine from Motion Industries. I was also able to get a CR seal by cross referencing the National #, the CR seal was a much better seal - double wall & double lip. Sorry, I don't have the CR seal number.
