Mines at 108, and looks/ sounds to be doing just fine. I've read about them
failing, so I pulled mine off the car and got it on the bench and opened
that bearing up. I cleaned it up, packed it with grease and put it all back
together. I'm hoping that will keep it going for quite a bit longer. I
figure the only thing that can really fail is that bearing, so as long as
you keep after it, you should be able to avoid a catastrophic failure. If
you catch it soon enough, I'd think you could replace that bearing if it
began to go bad and avoid having to replace the whole tensioner assembly.
