A few months back my vacuum pump disintegrated rather violently so this may be a suspect but this morning I found a .691" (17.5mm) ball sitting in the middle of the driveway. Having had a wheel bearing failure while driving I'd rather avoid any future bearing failures if possible. I know the wheel bearings are all roller bearings but where would I look for a failed bearing of this size?
