Chrysler 8.25in Bearing Kit

The Chrysler 8.25in Bearing Kit by Motive Gear is an essential component for anyone rebuilding or servicing the 8.25-inch rear differential found in Chrysler, Dodge, and Jeep platforms. This bearing kit addresses the critical need to replace worn or damaged bearings during differential overhauls, pinion bearing replacement, or when addressing play and noise issues in the rear axle assembly. Whether you're a seasoned DIY mechanic tackling a full differential rebuild or a professional shop handling multiple vehicles, this kit provides the precision bearings necessary to restore factory-spec performance and eliminate annoying differential whine.

Motive Gear has engineered this bearing kit to OEM specifications, ensuring proper fit and clearance within the 8.25-inch differential housing. The kit includes all necessary bearings required for complete differential assembly, manufactured from high-grade steel with precise tolerances to minimize runout and reduce noise transmission into the cabin. Proper bearing preload is critical to differential longevity—worn or undersized bearings allow excessive ring gear and pinion movement, accelerating gear tooth wear and creating the characteristic clunking or whining noise that signals imminent failure. This kit restores tight tolerances and eliminates play, allowing the gearset to mesh correctly under both light cruising and heavy load conditions.

Mechanics and enthusiasts working on Chrysler 8.25-inch differentials—common in first and second-generation Dodge Rams, Jeep Cherokees, and various full-size Mopars—will find this kit indispensable during restoration or when converting to performance gearing or locking differentials. Installation requires removing the differential cover, unloading the ring gear load, and careful measurement to set proper preload; this kit eliminates guesswork by providing factory-correct components. Proper bearing installation directly impacts differential efficiency, longevity, and noise levels, making this Motive Gear kit a worthwhile investment in any serious axle work.
