June 2008 lt I gt SPICER Drivetrain Products LUBRICATION SPECIFICATIONS Don t Neglect Spicer Driveshaft Lubrication Lack of proper lubrication is the most common cause of premature failure of universal joint kits and slip assemblies Properly sized Spicer U joints that are adequately relubricated at recommended intervals will normally meet or exceed fleet operational requirements Inadequate relube cycles and failure to lubricate the joints and slip spline properly not only cause joint failures but lead to other problems such as slip spline seizures Proper relubrication flushes the U joints and removes abrasive contaminants from the U joint bearings A Warning Inadequate lubrication can cause driveline failure which can result in separation of the driveline from the vehicle A separated driveline can result in serious injury or death In order to avoid driveline failure including driveline separation you must 1 Carefully review the lubrication specifications in this manual 2 Be sure that you use only approved lubricants 3 Be sure that you relubricate at recommended intervals Lubrication Procedure For Universal Joints Spicer replacement universal joint kits contain only enough grease to provide needle bearing protection during storage It is therefore necessary to completely lubricate each journal cross and bearing assembly prior to assembly into the driveshaft yokes Each journal cross lube reservoir should be fu
