Presuming that this is only a problem on the newer ones, have either the wheel bearing or the hub been changed or updated? I've done several wheel bearings In the grizzly's and all of them have required a press for removal and installation. I just can't see the wheel bearing moving unless the diameter of the bearing or hub has changed.Me grizzly, the wheel bearing is sliding back in forth in the bore because the bore has been drilled to deep, that is the problem. You cannot tighten this up unless you add a spacer shim behind the bearing, more risky in front of the bearing.
We are waiting on our resident machinist to get us a shim measurement, but he has grass to mow, trucks to work on and a day job to keep him sleeping in doors.
But I am sure this out of spec issue is driving him nuts and will soon be measured and spec' out. Lol
