I think I need to jack up the front wheel, slide a bar under the wheel & see if there's any up & down play. Is this correct? I'm going to a real mech. tomorrow, but would like the peace of mind tonight. How long will it last before it blows out? What would happen if I'm wheeling @ 60 mph & the bearing blows out? Is there a good chance of death? If so, maybe I should suggest the wife drive the J tonight.:lol::lol::lol: No really, that could be a problem.
