Differential Draining And Filling
CAUTION:
Do not fill the differential with lubricant up to the filler plug. The filler plug is only used to fill the differential with lubricant, not to act as a level indicator.
NOTE:
The only way to check the fluid level in the differential is to drain all the fluid out and refill with the correct quantity, shown in the specification section. See Specifications .
