GM 7.5 and 7.6 Differential Bearing Kit, ExCel XL-1044-1

ExCel XL-1044-1 (Richmond Gear) is a full bearing and installation kit for the GM 7.5 inch and 7.625 inch 10-bolt rear. It replaces Richmond 83-1044-1 and Motive Gear R7.5GRMK. This axle sits under a long list of GM cars and light trucks, including 1983-1998 Camaro, 1983-1998 GMC Sonoma and 1991-1996 Buick Roadmaster.

The kit has Koyo tapered bearings for the carrier and both pinion positions, a pinion seal, cover gasket or RTV, crush sleeve or preload shim pack depending on application, gear marking compound, a pinion nut, ring gear bolts and thread locker. That is the whole parts list for a regear or a rebuild on a noisy rear.

Use it when the rear howls on decel or accel, when you are changing ratio, or when the carrier bearings are pitted after running low on oil. Set depth, crush the sleeve to preload, shim the carrier, then check backlash and pattern. Backed by a 1-year/50,000-mile warranty from the maker.
