Front Rotor Runout

[benfield4]

Working on the 89 300 SE and I have a wobble when braking going down a hill or while on a freeway exit ramp. I did a complete brake job on this last year. Sounds like a warped brake rotor. The front drivers side runout is .009 inches. The passenger side is .001-.002. I replaced the drivers side rotor since its runout is excessive. I also had made a mark on the hub where the high side is on the old rotor. The new rotor runout is .006 at the same spot. This has me thinking its not the rotor but he hub or bearing. I set the bearings according to the service manual with the dial indicator. The bearings are original. I have ordered a new set of bearings for it but wonder if the hub could be messed up. I did not and should have ran the dial inicator on the hub itself to measure its runout. So I need to do that. Any other tests or ideas on what could cause the runout?

There is an 87 560SEL at the bone yard that I may pull the hub and bearings off of just in case and use to test with. That wheel shake is darn annoying.
