Here is what happened. I was riding around my buddy's property tonight when I hit some mud. I put it in 4Hi. The light came on like it was engaged, but it wasnt. It made some popping sounds but nothing that bad. So I stopped and tried 4Lo. Same thing. Anyone have this problem or can anyone help out.

 

what body style? If old body style, then it is most likely a leak in your vacuum line for the front diff to become engaged. Just do a search on it and you will find some good info on it. If you have a new body style, the default is locked in the front, so that wouldn't be the problem

 

She is a 04

 

It's probably the IWE Solenoid and the Hubs ...

 

Nice pic...

 

if it was an iwe solnoid, then it would fail safe in 4wd
if you are in 2wd and cannot hit 4hi or 4lo then you likely have a problem with the electric shift motor in your transfer case.

 

no... its like thump said.. its ether the iwe Solenoid or the hub actuator.. this is a beat problem.

I've been there, I've had it fixed on my 2004 F150. It's the IWE Solenoid and it'll cause the hubs to have problems as well. So both should be replaced.

 

If it was the electric shift motor the 4x4 light would not illuminate. From my past experience anyways. Thumper is probably right.

 

No the light came on like it was engaged but it just popped a couple of times.

 

It's your hubs and they probably are failing because a faulty IWE Solenoid. I went through the same crap on my 2004 F150.

 

by experience you probably need new integrated wheel ends iwe..

I've replaced 4 of em

 

I have the same proble, did you repair under warranty? Have an idea of prices? is something for do it yourself?
