OK, I'm sick of it, I'm tired of replacing seals in my axle. Well, 5 years ago I did the drivers side, less than 6 months later I had to do my passenger side, not quite 2 years I had to do the passenger side again, now I'm looking to repeat it. It really leaked today, on the way to church, the trip to mom and dads church has hills on the way, when I came to a stop, my van was engulfed with smoke from the gear oil burned off of the disc brake. I hate the 3:50 gears, it's too high for the weight of my van, I need 4:10, would help my MPG as stopping at red lights spaced every 75 feet, 8000 lbs unloaded takes power to get moving, just not able to buy a replacement axle, can't afford it. I have to fix this one, but would like it to stay fixed, what's causing the seals to go, could the vent be plugged up causing it to vent out the axle seal when hot?

The vent tube is clear, no blockage, the cover bolts were loose, now it's very low, lots of metal on the plug, clinging to the magnet, still no answer as to why the outer axle seal is leaking. Doesn't appear anyone else has a clue either.

Was a qt low of oil, when I redo it, I'll replace the bearings and brake pads, can't do it yet, depending on the idiots in office, have to put it off, I'm on disability. The seal surface was great when I did it, I'm ****, checked it closely, brake was fine last year when I did it, maybe it was the bearings, but they seemed fine, I repacked them and torqued to spec, same as the drivers side, did it in 2006.

Yes, it`s a job you would not want to do too often.
All I can suggest is that you make sure that the seals you get are made in the USA and not Chinese junk. Also lube the seal lip well with gear oil or light grease prior to fitting the hub. Maybe check the hubs for any play after a few thousand miles and retorque the bearings if necessary.
Good luck.

Yeah, not my first rodeo, have done the axles in the front of my 4x4's, requiring a real tear down, you lightly coat the hub with lithium grease to ease the seal on, as not to dragging dry. I always use brand parts, beware there are bearings with plastic cages out there, pack them by hand, expect to get dirty, I use vinyl gloves, turning by hand to feel that it's fully packed, fill the grove in the seal with some too. Torque after turning the hub with the nut snugged down.
