While your going roughly 5-10 mph, put the car in neutral and try putting it back in 4hi-free. You should here the click of the actuator and the light indicating 4hi should flash then hold steady. The car will lurch a little bit and you should put the car in drive. Accelerate lightly and you will be able to tell you're definitely not locked anymore. Please let me know if this helps.

if I ever need to be higher than 1st when I'm in 4low, I start in that gear. I am driving a 5speed Adventure though. But there's so much torque at that incredibly geared down speed, I'll start in 3rd no problem. I never shift to a higher gear while on the move and in 4low, because I also get that hard shift you're talking about. Not sure if it's doing any potential damage, but just doesn't feel good so I avoid it.

crap, didn't realize the age of this thread
