You're a bit off base. I can categorically tell you that bearings - once properly installed - never need to be adjusted. Bearings don't wear in the traditional sense, nor do they ever need adjustment. I'm not sure where you get that information.

With proper care, wheel bearings should last the life of the car. When I say proper care, I mean change the seals and grease at least every 60-90K. Most bearing failures occur because of improper mounting - not from wear.

About that wiggle you discovered... you have to narrow down where it's coming from. It could be from the ball joint.

With 85K, I'd say it's time to do the bearing maintenance. At that time you can inspect the bearings for spalling or imperfections to see if they are suitable for continued use.
