Build one if you have the resources. I had to have the top hole cut somewhere else because I do not have that big of bit for our mag drill but the rest was simple. I only used it on the truck pictured because that's the last one I've needed it for but after a lot of pounding and swearing, I built that, and it popped them right out. I'm not a metallurgist, but right or wrong I do know that extreme heat changes the properties of any metal, so on any truck with my name on the door, I will use that as a very last resort on things such as axles.
