Use the proper lubricantto purge all four bearingseals of each universal
joint. This flushesabrasive contaminants
from each bearing andassures all four bearingsare filled properly. Popthe seals, these seals aremade to be popped.
If any seals fail to purge,move propeller shaft fromside-to-side whileapplying gun pressure.This allows greaterclearance on thrust end ofbearing that is notpurging. If seals still donot purge, rock vehicle byreleasing the parkingbrake, start engine, puttransmission in D (drive)or R (reverse), and allowvehicle to roll. Thisremoves the windup in
the drive line and allowsfor a greater clearance onthe thrust end of theuniversal joint.
Because of the design ofthe universal joint seal,there will occasionally beone or more bearingseals of a joint that may
not purge. If this occurs,notify field levelmaintenance.
