the axle in my 9" rearend has moser 31 spline axles with sealed bearings with a o ring on the outside of the bearing to "seal" the axle when installed in the housing.
I am 99% positive it is the o ring leaking without having had a chance to take it apart yet. if the o ring is damage what would cause it? where can I get the correct size o ring to replace it?
if the o ring is not damaged, but is leaking should i put a bead of sealent in the houseing where the o ring seats? or should I just put a new o ring on, clean the housing end up good, oil the o ring & just reinstall the axle with no extra sealent on it?
is it very comman for this type of axle bearing with a o ring to start leaking . if the o ring looks fine what else could cause it to be leaking ? any suggestion or tips to make sure it doesn't leak. rearend has less the 2,000 miles on it since rebuild and new axles. thanks for any help!!! I don't want to have to do this again any time soon.
