Update:

Had the bearings/races replaced up front about a month ago while in for rotor/hat replacement.
Returned from shop, MAJOR shudder up front, both sides. Never a problem before.

Return to shop. Re-do of install and drive away.........shudder virtually the same.
Installer says he tried all possibilities and (if I recall correctly what he said) that each side is .005-.010 runout. Also turns out he hasn't done this project often.

Go to shop #2. Front (and now rear) bearings and races now replaced approx 2 weeks ago.
Those same 2 week old fronts were now worn to the point where they looked ~years~ old. Shop freezes/heats to get best fit, etc.

Drive away and shudder is virtually gone, barely detectable.
Seems a non-issue, so I do a track day.

Shudder is like a cheap hotel massage.....not good.
At this point I've spent over $1,000 on the bearings/races.

What do I do now? Hubs thrashed or ?
Anyone else been down this frustrating road?
