Re: Buying a hub puller
If you put a big strain on the puller, say 75 to 100 ft lb and then apply heat to the hub area, it will almost always pop off with no further abuse to the parts.
I leave the nut screwed on flush when pulling so the whole assembly doesn't go flying across the shop. (saw that happen and can be dangerous)
If you lap the hub to the axle when assembling, you greatly lessen the chance of key way problems.
What does this have to do with the first question? Nothing.
Any of the above named "clamshell" type pullers will do a good job.
