im not sure if this is normal but i was switchin in2 4x4 low at a stop sign before i went off into the dirt and what not and i noticed on my dash board. it still had 4x4 high on. it never changed in2 4x4 low. is this normal. this is my first 4x4 truck. alos while i was going over this 1 curb my underneath my truck i hit the curb with a bar or something about midway back on the bottom of my truck. it doesnt drive weird or nething but does ne1 possibly know what it was i hit/ should i worry bout it?

 

How can ne1 possibly know what u hit?

You have to be in park or neutral to shift into 4X4 Low.

 

well if some1 could look under there truck about midway back almost like dead center there is like a rail that goes from 1 side of the truck to the other. i was wondering if nebody knows what that is. and if so is it pretty durable. it scrapped at like 5 mph so.

 

Did you shift into neutral on the transmission before you shifted into 4lo?
If you didn't , it will not go into 4lo. All in the owners manual.

 

Sounds like you may have bumped your anti-sway bar. Is it tubular and kind of a bent shape?

 

I think what you hit was the transmission crossmember. The thing the trans is mounted to. No one can tell the damage unless they can look at it. It is pretty durable, but it depends on how severe the impact was. If it is bent more than the factory shape, its possible it might need to be replaced. Also if you didnt stop and put the trans in neutral or park it will not change into 4LO. Good luck and happy wheeling.

 

alright thanks for all the replies but i tried shifitin truck in neutral and park and both times 4x4 did not light up it kept sayin 4x4 hi. i guess ill just have to take it in.

 

I had this problem with my old 2001...the fix was to unhook the battery terminal for a few seconds. This resets the computer. Reattach and everything should be fine...except for the annoyance of reprogramming your radio stations.
