I used this to try to pull up windshield wiper arms that were stuck on the splined bolt (shaft), and was successful. Seems rugged enough, the little metal twist arm at the top lets you know if you are turning too hard. I used a penetrating lubricant on the parts first and let it soak in overnight. My experience: on the first wiper, after making sure it was secure, I got just to the point where I could not turn it anymore by hand, and the wiper finally popped up off the shaft at that point. On the second wiper, I turned it until I could not turn anymore, and had to very gently pry underneath the wiper with a large screwdriver (very carefully) and it popped up. I don't believe I could have got the wiper arms off in any other way. 5 stars!!
