Well, I ordered a HB from Rock Auto. A stock replacement; best one they had, if you can believe the data. Bonded rubber. Wish me luck. Ordered a new pulley for the serp-belt tensioner, too. The old one is dead smooth, but had some play. I remember replacing the bearing in it, myself, ???many years ago. So, my reasoning was that my DIY bearing replacement, with a sealed bearing of unknown pedigree and age, might be too close to EOL to ignore.
