As long as you go straight and don't turn the front wheels, you'd be fine. It's the same on a 4X4 rig no matter what kind, DON'T drive it in 4X4 on dry pavement, period. On a dirt road it doesn't matter as the turning allows the inside wheel to "slip" and catch up to the outside wheel. Without that slippage, as on dry pavement, you can snap an axle or at worse, begin to loosen the knuckle joints. Either way, bad news. The tennis ball idea is a good one. I find that in most cases I can just step on the rear dif lock and that usually takes care of most situations.
