    The forum is really hot today or maybe no one knows ...

    Asked this question yesterday and only got one response ...

    Can you look at a drive shaft and tell if it's balanced. Don't see how that's possible ... the dealer says they can.

    Don't I need to take it to a specialty shop to have it checked out?

    There are usually some weights welded to it, but they could be missing. they are usually toward one of the ends.

    Thanks 90k5,

    Weights are there, but how can you tell if it's still balanced?

    It's impossible to tell if it's balanced without putting it on a machine. If you get a vibration at increased speeds, it could be the drive shaft. But it could just as easily be the tires not balanced, or any number of other things. Look the shaft over for dents/ missing weights. If you find either, then that is definately your prob. But that is the only (eye ball only) way to tell if it's the shaft.

    That's what I thought! Been dealing with this woman service advisor! She's really believable, but just had to ask.

    Thanks,

    Bob

    What they probably meant by saying they can tell if it's balanced by looking at it is this:

    Driveshafts will have weights on them from the factory and it's not too uncommon to throw a weight, especially on a heavily used 4x4.
    So if the driveshaft is out of balance, you can look at it and see if all the weights are gone, or if one is missing (there will be a mark where it used to be)

    Thats the only way I can think of telling just by visual inspection

    Thomas.
