I still can't seem to get my 04 CDL to shift to the left to lock the diff either high or low, but it goes to the right high and low just fine. The wife is gone for the week and I've got some time to put into it. I was wondering if anyone has any tips on how to fix it. Do I have to pull the whole center console out? I have already tried spraying if with some PB blaster from underneath. Any advice would be great. Thanks guys.

 

Do you use it often? Sounds like the CDL cable is rusted up.

 

I recently purchased it used, 71,000 miles on it, not sure but probably not used much. If it is rusted what are my options? I was just outside working with it again, and it goes from high to low to neutral no problem, but no luck getting to the locking side.

 

Post a photo of your center console where the t-case shifter is, and the truck itself if you can.

 

Here is the picture.

 

I would agree with Mike then, sounds like your cable is seized.

 

If you want to tackle this, PM me your number and I'll call and walk you thru what to do.
