    I have a 95 IFS and while engaging the 4x4 it grinds and never goes into 4x4. I can kill the motor and engage it, but I am really not sure if it engages the front wheels, and it will grind trying to dis-engage the 4x4 until I kill the motor once again. Is this the actuator or possibly an t-case motor going out? :confused:

    No it is a manual floor shifter.

    Does it grind anywhere or only when you are stuck or in mud?

    My girlfriend's will grind occasionaly when I am stuck and push the button for 4x4. I put the transmission in "reverse" and spin the rear tires just a bit and it locks in.

    Maybe try to take out the front driveshaft and see if it still does it. If the noise is gone I would guess the problem is a front acuator, If you still have noise it could be a problem with the t-case (maybe just a linkage adjustment?)

    Does it grind when you try to move or when you are selecting 4x4 but sitting still?

    It will grind sitting still and trying to engage it in 4WD.

    I guess I will take the drive shaft out and and see what happens.

    I would guess it has something to do with the t-case. I'm not sure taking the driveshaft out will help.

    :( I am thinking that it is the t-case too.

    Thanks for the help!

    It may just need an adjustment, or maybe a shift fork is bent. I don't know too much about the internals of a t-case :crazy:
