The bushings in question cannot be beaten out; they have to be pressed out. And I hope you have an understanding significant other to be able to put greasy control arms in your oven (the truck won't fit, for the other frame mouted locations). You can use a MAPP torch, though.

To give you an idea of the force necessary to get the bushings in and out, I snapped a couple of Grade 8 bolts in the process.
