Hangar Bearing on 1992 GMC Sonoma

While having the oil changed, the Tech said that my hangar bearing was loose. Their mechanic looked at it and said that it was supposed to be loose. Are there any symptoms that I should be looking for? I certainly do not want the drive shaft falling out! Thanks!

I think your talking about the center support bearing and if the mechanic said it was fine it should be ok, when the support bearing needs changing usually there will be a vibration while driving.
