I realize this is a trailer forum but since I don't belong to any truck forums I'm posting here.
I've got a GM coporate 14Bolt SRW axle that is leaking out the inner hub seal on the R/H side. I've been fighting it all year. I'm sure it was doing this since new but since I don't drive the truck very often and I didn't catch it till this yr. Got a friend with the same exact issue and his is a 93... only 50,000mi same as mine.
First time I had it apart I replaced the bearing too as I noticed the inner bearing race was cutting into the axle stub flange and I figured it was under torqued from the factory. Well 2 seals later its still leaking and the bearings are still cutting into the axle stub flange even with the recommended 52'lb torque. I tried setting the seal all the way in and that helped but didn't stop it. The L/H side showed same bearing wear so I replaced them and seal also. No leaks before and now. Problem is on the R/H side only for the leak. Both sides for bearing wear.

Have the axle checked for true, if it is out it can cause short seal life & bearing problems.
