drive is needed.

Figure 4.

The transfer case has two gear ratios (high and low) and neutral. The vehicle must be

stopped before the transfer case can be shifted between ranges because the gears are not

synchronized.

Engagement of the transfer case in low range will automatically engage the drivetrain to the

front axles.

TANDEM AXLES AND SUSPENSION

Front and rear axles (1) are single reduction, full floating axle shaft type.
