I have a 3.5 ton floor jack that I think was like $99. It's about 5 years old. It worked great when I first got it, but within a year, it had gotten where I can no longer smoothly lower the jack when it has a load on it. (I can still lower it smoothly if it has no load.) If I jack up a car, and then try to lower it, I start trying to rotate the handle (counter-clockwise) and it doesn't want to rotate. So I have to use both hands, and get all worked up about it, and FINALLY it will turn and the car will drop - kerplunk.
Now, I also have a *really* old and really cheap WalMart floor jack, like 1 ton, that is old as the hills but I can lower it as smooth as silk regardless of the load.
Any idea what would cause the jack to not lower smoothly?
Thanks, John
