Gearcase Lubrication
GEARCASE LUBRICATION
NOTE: Dispose of used oil according to the environmental laws and regulations for your area.
LUBRICATION LEVEL CHECK FOR FRONT DIFFERENTIAL, TRANSMISSION, AND REAR
DIFFERENTIAL
Each gearcase component is equipped with two oil port plugs (1 and 2) (Figure 22, Figure 23, and Figure 24). When
the vehicle is on a level surface, use the level indicator hole (upper plug) (1) as a lubricant level indicator. Lubricant
level should be even with the bottom of level indicator hole (1).
LUBRICATION CHANGE FOR FRONT DIFFERENTIAL, TRANSMISSION, AND REAR
DIFFERENTIAL
Use the lower plug (2) for drainage (Figure 22, Figure 23, or Figure 24). Remove both plugs to allow the lubricant to
drain faster. See preceding NOTE.
Front differential:
Clean and install the drain plug (2) and washer before filling the front differential with new lubricant (Figure 22). Tighten
the drain plug to 108 in-lb (12 N·m). Use a funnel when filling the front differential through the lubricant level indicator
hole (1). See Periodic Lubrication Schedule on page 33. Tighten the level indicator plug to 120 in-lb (14 N·m).

transmission with lubricant. See Periodic Lubrication Schedule on page 33. Apply Loctite 567 to the threads of
the fill plug and tighten to 21 ft-lb (28 N·m).
