Ok jacked up the truck and engage 4x4 . I can sping the tire ( either one ) around and watch the front drive shaft spin . Problem is no 4x4 . I don't hear a clink like it went in at the transfer case . You think the motor at the case could be bad ? Should I be able to lay under it and get some to engage it and hear it move ? I fell pretty confident the front is working fine I think it's at the transfer case . Thanks for any help !

Vacuum solenoids maybe or engagement motor on the transfer case?

And if your lights in dash don't light those are the only two options I can think off.

Yeah I'm thinking maybe motor too . Everything seems to be locking up fine in the front . I can't hear the motor engage .

The light does light up but takes a few seconds to come on .

Ok , I jacked the front back up and engaged the 4x4 I felt and herd the motor on the transfer case engage . The front drive shaft is locked now . Now when I rotate the front tire the other one rotates the other way . Limited slip front end I'm assuming . So it should be working rite ?

I'm thinking sometime the motor work and sometimes not . What do you all think ? I don't have a problem buying the motor but I hate to buy it if I don't need it .

Front diff isn't LS. Its open. Deos your 4X4 work now?
