Spider gears allow each rear wheel to turn independently while cornering; over time, especially under heavier loads or towing, they can wear, chip, or crack, producing the telltale clunking noise on turns or a whirring sound that gets worse with speed.\u003c\/p\u003e\u003cp\u003eThis kit replaces the full open-differential gear set - side gears, pinion gears, and the cross pin hardware that holds them together - giving you everything needed to address wear without replacing the entire carrier. Because several of these platforms were also sold with a factory limited-slip 8.25\" axle, confirming that your differential is the standard open type (not limited-slip) is an important step before ordering, since the two use different internal components entirely.\u003c\/p\u003e\u003cp\u003eInstallation requires removing the differential cover and the carrier to access the spider gear assembly - a moderate-difficulty repair well within reach of an experienced DIY mechanic, and a common step during a broader differential rebuild or bearing\/seal service.\u003c\/p\u003e\u003cmeta name=\"description\" content=\"Upgrade your 1997+ Chrysler 8.25in axle with Yukon's 29-spline spider gear set.
