It seems that for as little 4xing I do, I am going through axle u-joints rather fast. I put on about 25K miles over the last 20 months since I replaced this u-joint but it was fine before the last time I used it on a trail. I bought a Spice joint for the longer life and it died before the junk one on the other hub! It still has grease in it. I have yet to get into water. and I always loose a cap!!! Is this a sign? Am I missing something?? Comments, questions and rude remarks welcome! Just help me fix this.
