   NOTE: Assemble rear axle shaft universal joint using the yellow snap rings supplied in the kit. If difficulty is encountered with yellow snap rings, install the black snap rings supplied in the kit.

8. Check rear axle shaft universal joints for freedom of movement. If binding has resulted from misalignment during assembly, a sharp rap on the driveshaft slip yokes with a brass or plastic hammer will seat bearing cups. Take care to support the driveshaft end and do not strike the bearings during this procedure. Ensure rear axle shaft universal joints are free to rotate easily without binding before installing driveshaft .
