    what could cause a vibration in the front end of the truck while under hard excelleration? I notice this when I went on to the highway with this truck for the first time. When I got to about 55 under hard exceleration I got all kinds of viberation in the truck. There was zero in the wheel. I am certain it is not tire balancing issue.


    I am open to all suggestions


    thanks

    what kind of hubs do you have? auto or manual, maybe you have them locked or something which would cause your front drive shaft to spin, which could be not balanced??? maybe check out your wheel bearing inside your front hubs?

    all have been great suggestions:

    the truck has no lift and the hubs must be automatic hubs(this is my first 4x4)I do not have to lock them in from outside of the truck.

    the only suggestions that I have not checked is the wheel bearing issue.

    How hard are those to get at? what is all inside the hub?

    well I fixed the worN-out shock mount and I still have the issue. There is no obviously bad u-joints. There is a bad lower ball joint with some play. Looking for Ideas.....

    Check out the stuff on the engine too, like the fan and balancer etc. If your only getting it during "hard acceleration" Maybe the faster engine RPM and imbalance is causing the vibration.
    You could probably sit in the truck and rev it up and feel it if this is the case.

    Finally got it figured out

    Well it appears the guilty colperate was a lose front left wheel bearing. This was something that I didnt think it would have been, but I tightened up that grease mess and things were good.
