Spline Differences for Older SUVs

The usual design showcases a total of four pinion gears as part of the planetary configuration.
Like most of the pre-1980 Jeep vehicles, the BW 1339 chain system was utilized until later developments were made. Because the shifter was mechanical, both 2WD and 4WD operation was possible.
