Anyone else here have problems with sector shaft seals blowing? My 94' loses one about every three months. Either it will start dripping or totaly blow out. Usually happens when I'm busting over a rock ledge.

I just hosed the second box in about 18 mos. I keep busting sector shaft bearings, which destroys the seal shortly after.

I think Advance lists a box for $140 with lifetime warranty and $200 core.
