Man, I had a nasty thing happen today. My LF wheel bearing on my truck failed spectacularly. NO warning, it just disintegrated inside the hub. Got positively interesting, I can assure you......I thought I was going to lose the wheel. Luckily, the 4WDhub and spindle both survived, so the repair was ony a couple hundred bucks, counting the wrecker, but it was still a PITA.
