Yes I replaced the bearings with new ones including the races in the hub, and packed them with MB grease, exactly the amount specified in the FSM. And I set the play using a dial gauge ... but had a little trouble getting consistent readings at first. I did finally find a position for the gauge that got consistent readings and set it as exactly as I could. Both hubs seemed to spin comfortably and evenly.

Both front wheels are definitely HOT. I drove it for a few errands to see what transpired and it felt OK. Just super hot when I touch the wheel ... I can even feel heat coming off. No smell anymore though. It is pretty hot out today (95 maybe?), and I know brakes do get hot, but ... . I'm driving the Jeep to work and I'll see what the Benz does tomorrow. I replaced a lot of things, so lots of room for error ...
