4.1 LUBRICATION PROCEDURE
WARNING
Read “Spicer Life Series Driveshaft Lubrication
Warnings and Cautions” in Spicer
Driveshaft’s Service Manual DSSM-0100.
1. Use recommended lubricant to purge all
four seals of each universal joint. This
flushes abrasive contaminants from
each bearing assembly and assures
proper filling of all four bearings.
WARNING
Maximum grease gun pressure should not
exceed 60 psi. Excessive grease gun
pressures may cause seal damage.
2. Make sure fresh grease is evident at all
u-joint bearing seals.
