Product Details

The ATP Parts OE Replacement Balancer, part number 102189, uses a hub-and-damping design to absorb crankshaft vibration and help maintain belt alignment. Over time, the internal damping material in a harmonic balancer can deteriorate, allowing the outer pulley to shift and creating belt tracking problems. This replacement is built to match original fit and function for the listed Mercury Villager and Nissan Quest applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
