I can get into low but CDL nipple just wont turn. i was trying to go clock wise.

 

Did you try counter clockwise?

 

Put the e-brake on, tranny in netural as well as the t/case, then try it clock wise only, about 45 degrees.

 

Spike I tried it going both ways, just to see if it would move and it wouldnt at all.

Mike I did have the parking brake on, and was in neutral/neutral... wouldnt go....

thing is it worked a couple months ago, and I changed the gear oil in the transfer case with Royal Purple 75-140 but neglected to lock it up and run it thru the hi and lo positions, forward and reverse like i did the first time i got it engaged.... I fear the worst as i just didnt use the CDL after lubing.

so if i can get into low but cant move the nipple, is it just a solenoid issue in there, or is the transfer case beat?

 

Ill try again tomorrow with in High and tranny in neutral, when the truck is cold

 

Try spraying it with penetrating oil.

 

okay, ill try doing that... transfer case has to work if i can get into lo, right?

 

so to sparay it with a penetrating oil, can I use wd-40? I have a fresh can of PB blaster if that wd-40 doesnt get er done.... just would like to use the wd up first

 

I got it! the wd-40 took a little bit of sitting and I was finally able to UNseize the pin and engage CDL... I thought it was messed up when i went to unlock it, because the light on the dash of axles didnt want to go out, but i got it to go out after i was sure i was all unlocked and went 30 ft straight ahead and it went out.... AKrover thanks for the idea man i was worried my CDL wasnt workin.
