A worn engine harmonic balancer can show up as vibration from the front of the engine, a wobbling pulley or a belt that keeps slipping or walking off. Before you replace the balancer, rule out the belt, tensioner and idler pulleys, because a tired one of those can make similar noise. The engine takes one balancer, mounted on the crankshaft.
Fits
The vehicles it fits include the 2011-2017 Chevrolet Caprice, the 2014-2017 Chevrolet SS and the 1997-2013 Chevrolet Corvette, and it is a direct-fit replacement for each of them. If your car is a different model, look up your year, make and model in the "Vehicles it fits" section.
