Hitachi R145 was used in 4WD applications as the rear final drive. Many applications used a 4-bolt rear cradle which contained the entire suspension except for the struts.

LSD

Can R145 use the R180 LSD?

Coupling

The coupling takes the place of a center differential. These models have a totally different case, which is split on the axle centers.

[edit]

Electric Coupling

The electric coupling is designed to work at any setting from non-powered to fully-powered, for various torque splits. The electric coupling, when not powered, allows the rear diff to free-wheel (putting the vehicle into FWD mode). When fully powered, the propeller shaft rotation connects to the diff as normal.

For this reason, operating as a RWD-only diff is complicated. You could use a relay and fully power it, but the failure mode would be to stop transmitting power.
