How much is your loader off? Mine was off 3/4". My dealer tried the uprights different loader booms ect and the best he could get it was 1/2 or so. I just sloted the holes one the high side upright and now its perfect. I think they said there was 1/4" tolerence or something like that. I'm not saying how i fixed mine is the best fix for every loader it just worked for me.
