I have an 04 2500 4x4. yesterday it just sudenly started to feel like it was i 4x4 on turns ,left or right. has there been a recall on the electronic 4x4 switch.

 

In regards tothis problem, I just had all the fluids changed(mobil 1)and changed as per owners manual. The manual says no limmited slip additive needed. Found thi not tobe true with the rear end. was wondering if thi could be the problem in the front as well. Some body must have some info or experience with this. Thanks.
