So last night I pulled that bearing - had to do some additional stuff to shift the #2 alt out of the way, but really wasn't too hard. Remove one bolt, loosen another, tilt the alt and then pull the bolt holding that bearing.
Interestingly, I found my other pulley in the grass about 10 feet from my truck. So apparently the pulley came off the bearing when I pulled into the driveway, which explains why I didn't get any failure lights from throwing the belt prior to that. I don't know what would have caused it to come off the bearing right there.
But anyways, since it had failed once, instead of pressing the bearing back into the pulley, I went to O'Reilly's and just bought another complete pulley assembly. Another $68, but what's that when you're already this far into things, eh???
So I got back, put it all back together and it fired right up, belt is tight, alternator(s) charging, no squeaking or squealing, everything is good. For now (crossing my fingers!). My friend is driving it to his job today, since this was all done in his driveway and I had 2 vehicles there. It was a bit late and I didn't want to drive home and then have my wife drive me back across town to pick it up, I was exhausted after a long day in the office, then physical therapy at lunch, then more office, then climbing in and out of the engine bay - a couple of Maker's Mark probably helped relax me to the point I wanted to do nothing but crash, also.
If everything continues to hold together well, the plan is to replace both passenger window regulators and motors this week, get a good detail job done if I can find someone to do it, and change out the 'break in' oil maybe Friday and leave for San Antonio to my grandmother's 95th birthday party. Wow. An 1100 mile break-in trip. I'm glad I threw the pulley at my friend's house 4 miles from home rather than in Dallas or somewhere along the way. Ugh, that woulda been baaaaaad.
We'll see how she does.
