Apply grease gun pressure and purge all four bearings until fresh grease is seen at all four bearing seals.
1. If a bearing will not purge, apply pressure to yoke lug ear opposite of non-purging bearing while grease gun
pressure is being applied. This should firmly seat the ujoint against the cup seal and relieve seal tension of non-
purging bearing. See Warning, below. Repeat procedure for any other non purging bearings (See Photo 1)
Warning - To prevent serous eye injury, always wear safety glasses when performing maintenance or
service. Failure to wear safety glasses could result in serious personal injury, and /or partial or complete vision loss.

2. If this procedure does not allow purging from targeted cups, attempt to relieve seal tension by one of the following
procedures:
For full round or inboard bearings, remove spring tab from non purging cup and apply pressure in opposing direction to
cup that will not purge to attempt to relieve seal pressure while grease gun pressure is being applied.
For ½ round or outboard bearings loosen bearing retainer from non-purging cup, insuring cup will not disengage from
u-joint cross, while grease gun pressure is being applied.
If all four bearings, purge fresh grease, replace removed spring tab and spring bolts and any loosened retainer bolts
with new. Follow procedure in service manual 3264-SPL for re-installation.
3. If the bearings still do not purge, complete removal of the universal joint kit is needed to determine cause of blockage.
See service manual 3264-SPL for proper removal procedure.
