Yesterday I decided to test the low range "L" on a street and did the same as the manual said "Stop the vehicle, put AT in N, shift 4WD lever from H to N to L". It worked well and I could feel little vibration when it went into L. Drove around several blocks, I could defenetly feel more power and torque while going up or down. When I wanted to put it back into H it was much harder for some reason to move it from L to N as if the lever was stuck in L. Eventually I was able to put it back into H (My hand slipped from the lever head and hit the 12V cover cutting my thumb). Also the lever head moves a little in H. Is it normal? I cannot remember if I could move it slightly before. Otherwise the vehicle drives fine now back in H
You drove around paved streets in L? Was the center diff locked also?
