First breakdown. Wheel bearing is smoked. There were two semis behind me when the bearing failed. Luckily I was able to keep it from darting off the road. Scary ****. Luckily itwas 2 miles from a gas station, was able to limp it here. I'm in Adrian Texas, 30 or 40 miles from Amarillo I believe. Gonna try to get some bearing brought out here.
Yeah we were real close to losing the wheel. I don't know exactly what happened, I didn't have noise, vibrations, or any warning. We were cruising down the road one second with no problems, then the bearing literally exploded with a loud bang. Only thing I can think is the bearing failed. When it came apart, it blew the grease cap off, and since there was nothing for the hub to ride on anymore, it was forced outwards into the nut. It sheered the cotter pin, and either the force of the car on the nut/washer shoved it forward, or it tried to spin the nut backwards and the force made it go crooked and stripped the outer threads. Whatever happened it was pretty violent. Felt like I ran over a brick in the road.
The important thing is everyone is safe, and the car is repairable. My wallet is taking a hit, but it will recover too
I had a similar explosion on a Toyota P/U. Fortunately my spindle was only disfigured a bit, some emery paper smoothed it out enough that the bearing went on.
That is when I got a clear visualization of "spun bearing". The inner race was actually spinning on the spindle and burnishing it because the rollers had fused.
Dang Don, that' crazy!! My inner race was seized to the spindle. Cutoff wheel and a sledgehammer got that off. Smoothed everything off where the outer bearing would slide on. Cleaned the 5 threads left with a wire wheel, loaded the new nut with loctite, threaded the nut on, and tacked it to the spindle in 4 places when I got it tight. It actually felt really good tightening up on the bearings, I was able to get it as tight as the passenger side. Went ahead and replaced all the bearings and races in the front.
I'm feeling much better about this spindle now, the nut went on straight, grabbed threads, and tightened up. I think I found a spindle at a junkyard in Amarillo, I'm gonna swing by and grab it if it's the right one. Be on the road shortly
