I put discs on last fall and one of the times when I got up from the creeper, I caught a flicker of daylight where it didn't look right. I had to move up and down a few times til I found where I saw the light and it was between the bottom leaf and the U bolt plate... OH SPIT! I got a wrench and I got 2 turns on those U bolts. The other three were somewhat tight but still nowhere near the tq spec. I'm just glad I caught it before getting the really effective disc job done and sheering that center bolt! Craig
