In years of working on vehicles I have seen several sticking calipers also with bad wheel bearings. We would have fun trying to analyze which did what first. Our conclusions were that the most common way would be the sticking caliper putting off centered pressure on the wheel and a "loose" bearing getting stressed. Loose could be a worn bearing or a loosely installed bearing or a cheap one with bad tolerances. You would now get a wobble vibration effect on the bearing further accelerating the breakdown. The strange thing is that we always saw this on either cars with radical rims/tires (which accelerate bearing wear) or heavy vehicles like vanagons. jimt On 7/31/05 1:53 AM, "Jeff Oxroad" <Oxroad@AOL.COM> wrote: > In conclusion, that original hot wheel seemed to be the bearing.
