universal joint. Carefully lower the driveline allowing it to rest in the driveline guard.
4. Wrap the universal joint on forward driveline with tape in order to retain bearings.
5. Moving to the rear joint at the axle housing differential, remove the capscrews that secure the yoke straps to the hub.
