At first, about 6 month ago, I thought it was just a fluke... I was out wheeling, doing some donuts in the sand, and noticed the left front tire wobbling a bit. After inspecting it, found that the TRE where it bolts through the arm, was loose in the arm. The castle nut still had the original cotter pin that I put in when the arms were first installed. No biggie, I just pulled the cotter, and torqued her down again. Now, 6 months later, I'm working on my hydro assist, and notice it's loose again /forums/images/graemlins/confused.gif /forums/images/graemlins/thinking.gif It looks like the metal in the arm is expanding, the TRE looks fine. I wonder what's going on? Has anyone else had this problem? BTW, D60, crossover hi-steer, moog TRE.
