b. On M936/A1/A2 series vehicles, lubricate transfer
case PTO universal joint every 3,000 mi. (4,800 km) or
3 months, whichever occurs first.
NOTE
Lubrication of universal and slip joints will be
accomplished while performing other inspection tasks
in that same area. Tighten, repair, and/or replace
components of universal, slip joints, and propeller
shafts when found to be damaged or worn, as required.
If maintenance is required at a higher level, records
should reflect closest point of reference to ensure
proper identification of components requiring service.
c. Lubricate universal and slip joints on transmission-
to-transfer case, transfer case-to-differential, differential-
to-differential propeller shafts, and speedometer adapter
every 3,000 mi. (4,800 km) or 3 months, whichever occurs
first.
d. Inspect universal and slip joints on transmission
PTO, transfer case FTO, and transfer case-to-front axle,
transmission-to-transfer case (para. 3-148), transfer
case-to-differential (para. 3-150 or 3-151), and
differential-to-differential (para. 3-144) propeller shafts
for damaged or worn components.
