Q: Belt pulley fell off car

asked by on

A belt pulley fell off of my car.

The moving components of the belt drive system use bearings to offer free smooth movement and reduce the effort necessary for the engine to drive the accessories. When the bearings fail, a pulley will often start to make noise or even fall apart. Have an experienced technician, such as one from YourMechanic, inspect the entire belt drive system. In few cases, a worn bearing can be uncovered using an automotive stethoscope. Any broken or worn components must be replaced along with the belt.
