I have been driving around the past couple of days with the bearings as they are right now and they are not getting hot, making noise and seems to be tracking straight down the highway.
Dave, drive to StL and back with them as they are now, and quit worrying about them. If you have parts in your toolbox, great. But don't waste time on your trip fixing something that ain't broke. You'll know if your wheel bearings start to go south -- you'll be able to hear it.
It's not an o-ring on the space shuttle. It's a wheel bearing on an old, super reliable Toyota truck that was made to be abused.




You definitely got your money's worth out of those. Did it spin on the knuckle? Kind of a roller bearing/plain bearing combo??
