How to Install and Setup Axle Ring and Pinion Gears

Once you are satisfied with the pattern, disassemble the rear end and install a new crush sleeve. Reassemble your pinion gear and make sure to use a new pinion seal. Reinstall the old pinion nut with motor oil and tighten until all play is eliminated from the pinion gear. Remove the pinion nut and clean the threads on the pinion gear and new pinion nut with carburetor cleaner. Then install the new nut with Loctite and tighten down until proper pinion preload is obtained. Mount the differential carrier, and torque the differential bearing caps down to their required specifications. It wouldn't hurt to install Loctite on the bearing cap bolts as well. Check your gear pattern once more to make sure that you reinstalled everything properly, and then check your backlash settings to be sure all is well. If everything is within specification, you're done with the setup of your new ring and pinion gears! Just be sure to not roast your tires for the next 300 miles while the new gear set breaks in, and you'll get many miles out of your new gears and axle.…
