So very true. Snap ot tools has a Blind bearing cup remover kit that would do the job, but I was concerned about scratching the hub or worse,warping the hub by striking it with a slide hammer style tool. I'm a Master Auto Technician by trade and have plenty of bearing pullers on hand. I just happened to put one together, jaws form this one a puller body from another one and a modify the jaws just a bit. Add some home made adapters....The one I made will work on many styles and sizes of cups with out having to make a different mandrell for every cup size. Also the one I have you can adjust the tension of the jaws so any cup will come out no matter how stuck it is. That's the difference in my tool. I will post all the pictures and parts on Monday. That way everyone that wants to make one can. BTW. There is one puller available today without any mods that will do this job. I just may post that one instead. Alot easier for many folks here.
