I tryed to do this wheel hop fix. I made problems for me. Tryed all bolts didn't move at all. Put penetrating oil on all four first one I go too spun one turn and stoped. ~~~ well then It spun freely the nut broke loose in the frame. I guess I won't be taking the other three out. Now the fun time of cuting the frame open to get a new one in there......just my luck.
