What are the symptoms of a failing/failed pilot bearing? I recently removed and re-installed the tranny/transfercase to replace the seals and when I tried to bolt them back on it didn't go smoothly. They're on and the leak is fixed but now I'm getting a funny clunking and squealing sound when the engine is under load while slowing down. Could it be the pilot bearing? Can I drive it this way or should I fix it right away? I have no idea what happens if the bearing gets worse and worse. Thanks. ....Steve
