Perhaps the wires going to the coils in the hubs are at fault. The plug in at the block as well. Is there any chance you disconnected one of them by mistake. If you cannot see readily what is going on, it might be worth starting from the bottom (hub) and working your way back up.

 

ok I checked the wires going from each front hub and followed them up to the wiring module (harness) everything looks fine. I did just put fresh oil in the gearshifter on the rightside where the linkage comes out there are three wires Could one of these be the culprit. The four wheel drive just started not working after I did this.What else should I check

 

Should not be any correlation between you changing the fluid in the transmission and the four wheel drive not working. My guess, if both front wheel are not getting power, then its probably an electrical issue. If you have a volt meter, with the engine on, and the gear selector in either forward speed, check the to see that power is leaving the box where each coil wire attaches. You should detect 12 volts going to the front hubs (boith left and right) when the AWD switch is turned on. If you get 12 volts there, then you need to make sure you are getting 12 volts down at each coil (inside the hub). If you are getting 12 volts to the coils and they are magnetizing, then you have a mechanical issue. But this is highly unlikely since I doubt both hubs would fail at the same time. My guess is that for some reason a lead or ground wire fell off somewhere and you are not energizing the coils when you turn the AWD button on.

 

I didn't change the transmission fluid. I changed the oil Where the gearshifter (f-r-l)is, there is a housing that has to have 10w 40 oil in it . If you will look or if you are familiar with it also has the linkage going to the transmission coming from it plus 3 wires. It a pain to take off but do you know what those three wires might be do ? Thanks for your help so far

 

Sorry, my mistake. I thought you meant the transmission in the back. As far as the gear selector - I am not sure. I guess technically something with the wiring could have gotten hay wire. Not sure how to diagnose that yet since I have never had it apart, but it does affect wheter AWD is on or not. That selector is 'smart' enough to know whether AWD should be on (in the forward gears and in reverse only when override is used). So, I suppose something could be hosed up there.
