I can get you an answer from one of my techs but im a bit unsure as to what is binding. Does it seem to be an obstruction insode the tube or the lower portion (the leg itself) bent? I can see if you can replace the inner tube with the foot or maybe a whole jack? LEt me know so I can try and get you the right answer first shot. Any pictures or model numbrs will help if convenient to pass along.
