I just completed a round trip of about 800 miles. Before the trip I rotated my tires and checked the front hub bearings by doing a vertical shake on the tires. They showed no play before the trip. As I pulled into town on the way back, I noticed the steering felt funny. When I got home, I checked the front bearings again. Now I have about an inch of play on the driver's side. I got new hubs and I'm putting them in this weekend, but I'm wondering, what if I had say, another 400 miles to drive - would the hub have made it? I think I may buy a spare hub to take with me on any long trip since this one seemed to go so fast. Just wondering if anyone has driven any big distance after they found out they had a bad hub.
