2. If any of the seals fail to purge, try to push the trun-
nion away from the bearing cup while applying
grease. On two side zerk fittings, try greasing from
the opposite side of the fitting.
Note: Due to sealing capability of the Spicer Life design, there
may be one or more bearing assembly seals that will not
purge.
3. If any bearing cup assemblies fail to purge, releasing
seal tension may be necessary.

It will be necessary to have addtional bearing retainer or
stamped strap bolts and stamped straps in order to com-
plete the following instructions.
1. Utilizing a brass hammer and wearing safety glasses,
sharply strike inboard yoke on lug ear once to firmly
seat bearing against spring tab and relieve tension
across span. Rotate shaft 180 degrees and repeat
procedure on opposite lug ear.
2. Apply grease gun pressure and purge all four bear-
ings until fresh grease is seen at all four bearing
seals.
3. If striking lug ears does not cause purging, remove
and discard spring tab bolts and spring tabs.
4. With a marking stick, paint marker or other lelegible
device, mark all bearing positions in relation to yokes
and bearing retainers at the effected universal joint.
This assures proper reassembly of the driveshaft
into the vehicle, in its original position. See Warning
Below.
Reassembly of a driveline out of original phase can cause
vibration and failure of the driveline and attaching compo-
nents.
5. Working at the effected universal joint, support the
driveshaft with a support strap. Attach support
straps to frame rails or some structural part of the
vehicle.
6. Remove the bearing retainers and bolts at the
effected universal joint.
Note: New cold formed bearing retainers DO NOT need to
be replaced. Replace only if damaged.
