Can a bad pulley cause squeaking?
Worn/Cracked Serpentine Belt – Serpentine belts have grooves which fit into grooves in the pulleys. Over time, the friction wears down these grooves, resulting in a loose fit. A worn belt can, therefore, begin to slip, which is one of the causes the squeal. A bad pulley can cause slippage or misalignment.
What does it mean when a pulley is squeaking?
Friction. The squeak you hear is generally a result of the belt losing its grip on one or more of the pulleys it is designed to spin. It could be a symptom of a worn belt. The contact surface can become worn and smooth, which lowers the friction point and causes the belt to slip.
Will WD-40 fix a squeaky belt?
