hiya
this is the same bock my spring snapped on bout 4 months ago. ita neva been rite since.
i followed the tutoral about using the paper clip and string to make sure the bock is in line,it was off but i sorted that.
ive checked all the nuts and bolts they are ok ,it was only moving very slighty at 1st so i neva noticed it,but now wen i put the pro jump on my whole leg n hip twist out n i can move the calf cuff bars just by pulling them apart even thought they tight.
(there only bout 1yr old )
i tried to upload a pic but it wont let me
