actually the elim doesnt rest on the 1/4" (measured from the flange) that you leave , if the brearing portion does contact the part sticking out (if you left it too long) the elim will not last long , the bore size of the recess in the elim housing is larger than the axle tube and youll notice it can float side to side a little
your options after the failure of the moser eliminator on moser perf axles is to
replace the eliminator (they only sell as a pair at just over 150 bucks, but youll have a spare for when the other one goes ). i can tell you when they do leak they are a pain to get off , easy way is cut the outer shell off then cut the bearing outer hub off then cut a deep groove i the race (dont hit the axle ) and then split it with a chisel . alternative would be send it to moser and let them fix it
replace the axles and elims for better design eliminators as mentioned above (330 for the pair of axles and 170 i think for the strange elims )
or go for the ford style (GM) ends
