To get to the rear axle 248RBI, you first remove the wheel and tire, then the brake drum and axle shaft. After that, unbolt the lock wedge and adjustment nut with Socket DD-1241-JD and remove the hub assembly, so the outer axle bearing can be taken out. Remove the axle seal with your hands and then drive out the grease seal and axle bearing inside the hub using Installer 6064 and Handle C-4171. Tap on the bearing cups from the hub bore using a brass drift or a suitable removal tool. Clean the axle bearings and the inside of the hub with the proper cleaner, then install the bearing cups using Installer 8151 and Handle C-4171. Fill the inside and outside bearings with Mopar wheel bearing grease and then grease the surfaces of both bearing cups. Replace the inner axle bearing in the hub, then use Installer 8149 and Handle C-4171 to fix a grease seal in place. Examine the contact surfaces between the bearing and seal on the axle tube and if you see roughness or burrs, remove them. Align the hub with the axle and watch to see that the grease seal does not touch the threads on the axle tube during installation. Installing the outer axle bearing, then hold the nut of the hub adjusting ring with Socket DD-1241-JD and tighten it to 163-190 Nm (120-140 ft. lbs.) as you turn the wheel. Give the nut 1/8 to 1/3 of a turn to set the wheel bearing end play to 0.025- 0.250mm (0.001-0.009 inch), then slide the lock wedge over the spindle and the nut into its new location. After the above steps, put in the axle shaft, brake drum and wheel and tire assembly.
