Hello, I have a 1991 f150 with the 5.8 motor. Ever since I got it I can't seem to get it to go into 4x4 low. (It has the manual 4x4 shifter on the floor) it will pull back into 4high and 4high works but I can't get it past that. Can't even get the 4x4 shifter in to neutral. What are some things that can cause this or ways I can fix it. Because I live in northern Michigan and with winter coming up I really want to have 4low incase I get in a sticky situation in the snow. Oh and yes I know that the truck has to be in neutral to shift into neutral and 4low on the 4x4 shifter. Thanks in advance for any and all help!!!

 

try it on a slight incline, the last 1356 I had thats how I had to get it to engage, just let it roll sightly while you pull it to engage.

 

dumb question, but are you pushing down on the shifter when pullin on it?

 

The shifter doesn't say push down. But I have a friend that has a 97 that you have to push down it get into 4low so I have tried both pushing down and just pulling back but neither of them work to get it into 4low.

 

Tried it on an incline. Still won't go past 4 high.
