Default wheel wobble /BAD DRUM resolved

OK, Just back from shop (with lift). Had two new drums delivered. As previously noted had replaced the axles yesterday and they were in fact bent. New axles are right on the money when car in drive on lift. Can't even tell they are spinning. Put new drum on. same thing. wobble. WTF? Put second new drum on. Oh My God, no wobble!!!. Here's a shocker, Apparently there is no quality control in China where these are made. Some are true and obviously some are not. Just to check, we put on the old and the other new drum and wheel wobbled with each. Put other back on and going with same. Apparently you need to order about half dozen drums and try to find the one that is best!!!!. Wish I could find some NOS somewhere.

You could chuck the drum up on a brake lathe and measure the run-out. I have done tons of brake jobs over the years, and in the past ten years, have run into a LOT of drums and rotors that had excessive run-out right out of the box. This is caused by poor manufacturing, rough handling (dropping the drum/rotor while it is boxed) or both. No way to really 'fix' a warped drum that is warped at the flange, which sounds like what yours is. I'd keep returning defective drums until you get one that runs true. Or try to find a decent used drum.
