What causes a belt tensioner to bounce?
Excessive arm movement or bounce due to a worn damper: The damper moderates the action of the tensioner spring in much the same way that a shock absorber dampens a vehicle’s suspension. As the damper wears, the tensioner arm can bounce away from the belt, causing excessive belt slippage.
What can I put on a squeaky belt?
