Is the 4WD light on indicating that it is actually in 4WD? Even if it was in 4WD, you should be able to get it above 10mph. Unless it is somehow in 4 wheel low. Which it shouldn't be. Is this the electronically engaging 4WD? Most people rip those out just for this issue. They put in the old manual hubs instead. My grandfather got rid of the electronic nightmare and put in the old locking hubs. But most likely it's you Transfer Case Control Module that is bad. It should be located behind your passenger side kick panel.
