All Durangos will be equipped with four-wheel drive for 1998, but two transfer cases are offered. Both systems use a manually operated shift-on-the-fly lever mounted on the floor.
A part-time four-wheel-drive transfer case is standard. Shifting into part-time four-wheel drive is only appropriate for mud, snow and other low-traction situations; it's unsuitable for dry pavement as there is no slippage between the front and rear wheels and the tires will hop and chatter in tight parking lot maneuvers. It's a good setup for people who live in a dry climate, but want to be able to shift into ultimate off-road mode. On really steep grades, it can be shifted into low-range four-wheel drive.
A more flexible option is the $395 full-time four-wheel-drive transfer case. It comes with everything above plus a planetary center differential. Shifting to full-time mode allows the front and rear axles to turn at different speeds, so the wheels don't fight each other in tight quarters yet traction is assured under all but the worst conditions. Full-time four-wheel-drive mode is appropriate for torrential rain, light snow and ice or light off-highway travel. If conditions should get extreme, the driver can shift into part-time four-wheel drive or low range. Next Page
