May be OK in N/2H, but safest to pull the 4 bolts at the rear axle and hang the driveshaft up. Why?

Gear driven cases use the input gear and low range gears to throw oil on the inside of the housing that collects the oil via gutters and directs it to the rear of the case by gravity. Both style of cases, must have the input shaft spinning to lube the output shaft, speedo gears, and rear seal of the t/case. The rear driveshaft must be removed.

I kind of look at it this way, with the driveshaft disconnected, it is 100% safe, with it connected there is a chance of problems. Many folks do it w/o issue, but some have trouble. There are a number of threads on the Pirate4x4 forum (where the above quote was found), recounting flat towing problems with the driveshaft connected.
