So, when I replaced my axle shaft last fall for snow plowing, i confirmed it had no play and was greased, as I did the same to my driver side u joint. I did about 8-10 hours of plowing all combined last winter, and right now my u joints are barely holding on. Most of my snow plowing was done in low speed, if that matters. To me, this just seems... insane that the u joints are so worn out and almost on deaths bed already, Id hate to pull the shafts and put new U joints in just to do the same thing next summer, if this is caused by something else. Is there anything I should look at for what is causing it? Or, perhaps, should I look for beefier drive shafts? I found a set on 4wheelparts.com that have good reviews and people say the yokes are beefier and the u joint is beefier, but is that a bandaid on another issue kind of thing? I know turning in 4wd and the fact I have a large, heavy bumper and a heavy iron plow im sure put a lot of stress on the front axle, but to me, one season of mild snowplowing seems insane quick to eat u joints.
