Hi while I'm waiting to be able to sign in to forum again I thought I would post here.Is there any way to tell if my transfer box is knacked or its something else wrong.The truck runs great in 2WD but when I put it into 4wd it's like something is jammed and won't move. It is an 07Warrior with super select box. Thanks

Check the oil levels first

I will thanks Nick I'm not much of a mechanic but that I should manage 👍do I just take out fill plug and see if tho oil is level? Second thoughts I will change all oils if I can.Need to go and buy a socket set now.

Make sure you get the correct grade oil, its in the handbook.
Yes its dead easy to top up.
