3.0 automatic belt tensioner

[Vilpo]

Anybody had these going bad?
Mine is way off the belt centerline and belt is already a bit over the edge of the tensioner.. Is it possible there is a bearing gone there or something?
Is the tensioner difficult to take out for closer inspection?
The belt also squeels on the alternator pulley, and i'm guessing this is causing it since the belt is just few months old..
Any help would be appreciated.

Edit:
Forgot to mention, I'm talking about the serpentine belt tensioner here.

yes they do go bad and can screw up your serpentine belt if they wear out.


btw, i have a brand new one on my old 12v i could sell you....bought it for 75 at autozone, 35 + S/H?

Ok, thanks for the offer but i found the problem and something to fix it, for now at least..
It was easy to take out, just one bolt open from the other side of the bracket, and it came out.
Now the problem was, that the steel plate, that holds the tensioner together, had bent and made it loose.. So the pulley would twist to the right/down a bit. Now there is a hex screw in there to tighten it, but it had stuck on mine so i couldn't use it. So i solved it just by placing two small steel sheets as a spacer between the lower part of the tensioner and the bracket. This would correct the tensioner position just enough to make the belt run in correct alignment. Now the belt stopped squeeling right up.
But i guess the best solution would be to adjust the screw if someone else has this problem..
