My belt tensioner is chattering a little bit and I'm wondering if I can just replace the bushings? How will I know if the whole tensioner needs to be replaced?

This has likely been covered before but I couldn't find it. Thanks

 

The tensioner comes as a complete unit- you cannot buy pieces for it. I'm not sure what bushing you're referring to though? If the tensioner shock is blown, bearing has failed, and/or belt is not holding tension, its time to replace it.

 

I'm referring to these bushings from Way.

Powerflex Damper Bushings

 

Way has delrin bushes that he says are better than Polyurethane.
