Unless he's using force greater than like 500 lbs per hit, I'm fairly certain he'll be fine. You don't need to pound on the rotors anyways. Several moderate taps should do it.Just keep in mind, the more you pound on the rotor the more stress the wheel bearing is taking. Any time you hit the rotor/hub, you are stressing the entire suspension. This is not to say you are ruining your suspension, but another way to get it off is to heat it with a torch around the hub, and then cool it with water. If you don't have access to a torch, try putting a big pry bar between the hub and rotor(be sure not to bend the ears on the hub), and keep rotating the wheel and prying some more. Although you may even have it off by now lol.
competely agree with john, heating it up is one thing but when you rapidly cool it it'll become way more brittle than it's designed to be.And cooling with water sounds like a horrible idea. Maybe its just me but rapidly and forcefully cooling metal doesn't sound like a good idea to me at all.
loland if hammer doesn't work get a bigger hammer lol.
Whats gonna become more brittle? The rotor, hub, or both? I'm curious because I have always done this and no one I know has told me that before.competely agree with john, heating it up is one thing but when you rapidly cool it it'll become way more brittle than it's designed to be.
Then thats good to know I guess. I remembered that I work with a guy who knows a really good welder, so I might ask him this weekend.heating and rapidly cooling any kind of metal will change the composition of it. i'm guessing since both the hub and rotor both get heated and cooled pretty much at the same time they'll both become more brittle.
