I have one of these Smiths Stevenson jacks and it runs smooth for most of the way, but about 23rds in it binds and is hard to turn. With leverage it is possible, but should not be like this.
Has anyone ever fixed this type of problem OR better yet replaced the screw mechanism in the original body? I have several old screw-type mechanisms that should fit inside the body with some fettling.
The jack seems to be welded and crimped together, but you innovative types out there might have done this with satisfactory result no matter what it wound up looking like. My car will not be concourse or shown to any degree.
If anyone has any or all of this info, please tell me. Thanks
