Four-wheel drive vehicles can become stuck in four-wheel mode due to improper lubrication or lack of use. This is a common problem and is usually not a very serious situation. It is important that you switch to two-wheel drive when you transition to a hard dry surface, as operating in four-wheel drive mode on the highway will decrease fuel efficiency and can lead to damage.
Step 1: Check to see if you have manual hubs and that they are in “free” mode.
Step 2: Put your vehicle into four-wheel high mode.
Step 3: Drive forward for about a quarter of a mile.
Step 4: Stop the vehicle and shift from four-wheel to two-wheel drive.
Step 5: Place the vehicle in reverse and drive backwards for 15 to 20 feet.
