Reply to "Really inexpensive rear axle socket removal tool"

Its not secret, but a few things cut down damage in pressing it apart. First, the assembly weighs 65 lbs and has lots of protrusions to snag the unwary human. Get some help if balancing the assembly in your press is a problem. Second, knock all the wheel studs loose first; they won't come all the way out, but when you press against the rotor you're not only trying to push the axle through the press-fit bearings, you're also trying to press all 5 studs out at the same time. And be careful in knocking them back- hit straight with a brass hammer or with a chunk of aluminum on a stud so you don't mash the threads. Wheel studs are hardened & do not bend, and cost $16 each to replace if you crack one.
Third- ideally you will use a big circular stand-off fixture that contacts the rotor at the rounded-off area inside the point where the pads touch, not out on the brake pad area. If you use two simple parallels across the pad-wear area and the axle happens to be very tight- or you didn't knock the studs back first, its possible to break a rotor in 2 or 3 pieces with a 12-ton press! I made my fixture from a piece of 6" dia cast iron sewer pipe, and vendors use similar fixtures of 4" thick Bakelite plastic, or even wood. 12 ton presses work fine. If your assembly seems to need more, there's something binding up. STOP and check everything before adding more pressure!
