I am looking at purchasing a lift, but when we tried driving it, the front right tire binds when in reverse and starts to drag. Everything works fine moving forward. When in reverse it does start to roll slightly but then binds. It doesn't lock up completely, and will move a little bit as the rest of the forklift moves, but causes the whole forklift to move somewhat sideways. Any thoughts would be greatly appreciated. Just trying to determine if it is worth buying at a great deal and fixing myself.
