sorry meant worm block...thats what we replacedthankyou everyone for your suggestions we have replaced the worm plate screw thingy which was split and will re-attatch the leg this weekend fingers crossed we can get it back on thanks
not sure but on 1987 vans there was a plastic bush that the screw goes through.these ware or split,you change these yourself for about
This happened to me last time I used the van my wife had lifted the leg and had over done it, when we got home I went to lower the leg and it would not move. On closer investigation I found that the worm block at the top of the leg had split allowing the worm thread to just turn with out the leg moving. I phoned Barrons who said they keep them in stock cost me
