I wanted to take a front disc off to replace the plate that is behind it. I took the Warn hub out and was supriced that I could srew both those funny looking nuts out. The ones keeping the bearing in you know! They were not tightend at all. But I can't see anything, or took out anything that is suppose to keep them from comming loose. Can anybody help me on this? How is it suppose to be. I have 2 Hayes manuals but both only look at the 2wd front bearings. Very weird.
