    I have a 2004 Chev 3500 Crew Cab with the Duramax/Allison combo. Should I be able to move my drive shaft by hand with the truck off and in Park?

    cet, could you give us a little more detail's? When you say move, in which direction does it move,up and down,or are you twisting it? And where is the movmen? At the tranny, at the carrier assembly or at the rear?

    B&B I have everything fixed. Actually nothing is broken. The movement I was refering to was rotating the drive shaft. For what it is worth you should be able to rotate(twist) your drive shaft a little bit if you put your truck in neutral and use the parking brake and then put it in park. I was refering to the rear drive shaft. I am refering to a rotation of only 1/2" nothing major.

    They removed the drive shaft and checked all universals with no repairs needed. I plowed with it yesterday for 10 hours without a problem. I have no idea what happened but they are guessing computer glitch.
