    what the best method to measure axlehousing straightness? looks like my rear tires might be slightly bowed in at the top, not sure if this is an optical illusion or not. i'd like to measure it somehow to be sure. whats the most accurate way?

    Same way you checka frame for straightness Jon.... take measurements at the top of the diff to the flange and bottom of the diff to the flange.
    I think this may work, maybe not.

    A four wheel alignment would let you know.

    Pull out the axle shafts and look through the tubes.

    If it's a 10 bolt, wouldn't be surprised if it's shaped a little like a taco. Mine did that on 31's. Alignment shops, particularly Sears, you can get a free alignment check. When he's got it on the rack, ask him to show you what the rear camber is at. He'll tell you he can't set that, but you want to see it anyway. Negative camber on both sides = axle shaped like taco

    never knew sears gave free alignment checks. sounds like that would be the most accurate way to tell if its bent.thanks guys

    at work we print sears's auto service checklists we got a big order from them recently and are setting up a machine for it.

    ive had a 7.5" 10 bolt axle have the tubes come loose from in the diff housing and it was bowing reallllll bad, the tubes were coming out, it stil drove but would grind the drums on the plates

    ive never seen it happen on an 8.5" but i guess it possible

    those weld plugs seem to work loose


    sound slike yours has done it

    id like to confirm it if so, cuz ive never seen it happen on an 8.5

    if it has happened then you wont be able to miss it, when you look at the axle, it wouls be plain as day that the center of axle assembly is bowing down due to loose tubes.,


    good luck

    i dont think thats the case on my truck. if you look at the axle itself it looks arrow straight. but stand back 20ft behind the truck and looks like either tire is bowed in a bit. i'll check closer tomorrow tho..

    my front tires seem to be bowed out on the top more than the bottom, and I am seeing some wear on my tires.

    is there any good reason not to weld the tubes to the pumpkin?

    ya, the housing is castiron, tube are steel. they expand and contract at different rates, potentially caussing the welds to break. that why they are only plug welded in the first place
