Hello. New too site. Looks really guys. I think its well put together. Anyways ive been driving and building quads for awahile but ive come to a brink wall. I had bad rollover going high speeds on a river. The quad came out not too bad. ive fixed it next too new. Just one part. My swingarm barrings went loose and ive got into repairing. Theres a locking nut one side of the arm. with 4 points. WHY? I cant find one anywhere. How did you guys get around it. If your anything like me, i make my own tools through metal fab. This one would be tougth. Any idea?
