A squeal or chirp from the belt area, or a rough bearing noise, can mean this pulley is worn, though a stretched belt or a failing tensioner assembly can be behind them too, so find the cause before you replace it. Quantity varies by vehicle: the 2012-2025 Jeep Wrangler V6-3.6L takes one or two depending on the year.
It fits a wide range of Jeep, Hyundai and Volkswagen models, including the 2011-2019 Hyundai Sonata L4-2.0L and L4-2.4L and the 2005-2014 Volkswagen Jetta L5-2.5L.
