Hello everyone,
I am new to the forum. I have a customer that call me and has a Pete that the 4x4 is not engaging. I have not seen the vehicle in person yet. Does anyone know of some common issues of the 4x4 system not working properly. Its been years since i worked at Denver Peterbilt, so i am out of the loop on the newer vehicles. I would think that the system is air engaged with electric switches.Please let me know if you have any info on this issue. Thank you for your time and tech support to fellow mechanics.
