    I had a little bit of play at my power divider, 3 months later it took a dump.

    This is in the output shaft coming out of the rear of the front diff. The power divider has already been replaced.

    Well, not sure if its related, but i had a CEL come on this afternoon. Gave me a 95 code for the IVA oil pressure sensor. So tomorrow i will replace it and see if it fixes anything else. Cat said it might have something to do with my vibrations if it wasn't allowing the variable valves to work properly. I guess we will have to see.

    Yeah the final straw that made me realize it was engine related was last thursday morning it did it like normal. But this time it all of a sudden went completely calm and the engine got quiet. I looked at my boost gauge and it was only at about 25-30lbs, should be 35-40. So i knew i wasn't getting full power. One of the problem injectors had completely stopped working instead of partially working which was causing my vibration. So when it cut out 100% the vibration instantly disappeared. It also passed the cut out test at Cat. It wasn't until they tore everything apart that they found the issues. Thanks again to all for the help!
