• Description:

  This genuine Mopar drive pinion bearing kit is engineered for use in selected Jeep, Dodge, and Ram axles and includes the inner pinion bearing and its matching bearing cup. It is intended for applications with the DMC 3.21 rear axle ratio and DS7 conventional front differential, making it suitable for many Jeep Wrangler and Wrangler JK models, Jeep Liberty, Jeep Grand Cherokee, Dodge Nitro, and certain Ram 2500 trucks listed for this kit.

  The drive pinion bearing supports the pinion gear inside the differential housing and is critical for maintaining proper pinion preload and ring‑and‑pinion gear mesh. Worn or damaged pinion bearings can cause gear noise, vibration, and premature gear wear. Replacing the inner bearing and cup with the correct OEM components during a differential rebuild or gear service helps restore quiet operation and long‑term durability.

  Fitment for this kit spans multiple years and engines, including 2001 Ram 2500 5.9L diesel, 5.9L gas, and 8.0L V10 in the specified axle; 2001‑2018 Jeep Wrangler and Wrangler JK; various Jeep Liberty and Grand Cherokee trims; and 2007‑2011 Dodge Nitro in the noted axle configurations. Always verify compatibility by VIN or parts catalog, and confirm axle code (such as DMC and DS7) before installation. To help ensure proper fitment, entering your full 17‑digit VIN with your order is highly recommended so the part can be verified for your specific vehicle. Order today to get the correct OEM pinion bearing kit and avoid the hassle of returns or improper fitment.
