I have this truck and I can't figure out how to put it into 4wd and I NEED it for my job...help!!!

First of all, I would read the owner manual. Second, if you don't understand the manual consult a mechanic, dealership or other experienced driver.

This is how I shift my 2005 ram into 4-hi:

while driving at a speed of greater than 15mph, reach down and shift the selecter lever into the 4-hi gear. For shifting into 4-low, I start the vehcile, shift the transmition to neutral, turn off vehicle and proceed to shift the selecter lever from 2-hi to 4 low.

The 4x4 gear shift is located on the floor right? after you have the truck running, and parked, just shift it into either 4low or 4hi(for highway driving) When you dont want it in 4x4, you can shift it into 2hi at any time.

hope this helps

I own a mustang and I don't know but if I were you I would take it to a dealership or ask someone else that you know with this model and find out if they can help you.
