    Alternator bearing help!

    Ok. My 99 WS6 has torn through 3 alternators. It just chews through the bearings. My OE died at like 126k. I bought a AutoZone reman. 2 weeks later, bearings are gone. Got another one under lifetime warrenty. Bearings were blown as soon as I turned the car on. So I got pissed and bought a BOSS HO 160(amp?) alternator. It has worked for 2 months. Now the bearings in it are shot. It's squeeking like your moms loose bed frame.

    What would cause a LS1 to chew through alternator bearings. Because I have replaced everything ( idler, tensioner and pully, belt, water pump, alternator a few times ) so I don't know what is going on. Please help!

    Nah, the bracket is brand new. I seriously have replaced everything on the the front of that engine minus the ps pump and the crank pulley. :\

    How tight is the tensioner on your car and what kind of tensioner?

    It's a brand new stock tensioner. Got it a month and a half ago. It's pretty tight.
