The Ranger rear ends for 31 spline 8.8's have a WMS-WMS (wheel mounting surface to wheel mounting surface) of:
58.5

The expo 31 spline 8.8 has a WMS-WMS of:
59.625

Difference of 1.125 total, .5625 a side.

The Ranger axle shaft for 31 spline  length:
RH 27.25
LH 30.125

The expo:
RH 27.62
LH 30.5

RH Expo is .37 longer, plenty of ground bearing surface to fit the Ranger.
LH Expo is .375 longer, plenty of room on the bearing surface to fit in the Ranger.

Where did the extra .38  go? (.745 axle shaft length, 1.125 WMS to WMS)
