4WD Issue, Truck Bucking

[JBonpua]

Today in a large empty parking lot I switch (electric) my truck to 4L. To my surprise the 4WD just flashed and did not stay on. I made a turn and the truck bucked like a bronco engine RPM going up and down. I tried 4H but did the same thing. Last time I had it in 4WD and made the turn it made just a little expected binding sound.



Any idea what is wrong?

On a high traction surface (asphault) it will buck like that when you tun in 4wd. The only problem you have is the indicator light that didn't stay on.

Got it figured out. It helps if you read the manual. I guess when I did it the transfer case did engage but the electric 4WD did not finish its thing hence the flashing 4WD. I knew the transfer case engaged but my concern was the flashing 4WD. All is well no and thank you all for the reply. :-laf

My 06 is tricky to get in 4 low.
If your switched to 4 low and 4low light is flashing it means your not fully engaged.
Rock the truck back and forth or put in nutrel and shut it of and restart,put in drive till 4x4low light stays on steady.
