Hi, I've noticed a strange vibration coming from the serpentine belt tensioner. It's not constant, but it's like an oscillation.
The alt pulley was changed last year, also the shock absorver and the return pulley were changed when the alt pulley was changed. As for the tensioner, I think it's the original one, and has a little play between the fixed part and the moving one. Should I replace it? The oem one here in Argentina has the ridiculous price of 130 usd.
