    I have my front axle down to a bare housing and I want to be sure the housing (tubes & knuckles) are true before I put a bunch of money into building it.. My reason for questioning it is for years I have had a wobbly/hoppy front end and EVERYTHING but the housing has been replaced. and I mean everything, including the frame, steering box, ball joints, shocks, steering braces, tires, wheels, brakes, rotors, etc etc etc ETC


    should the tubes be DEAD NUTS parallel and straight w/ each other? How close is close enough? Anyone have any measurements from a reliable source? like center of ball joint to center of ball joint? orrr??? My GM manuals have exact measurements for checking the frame for straight.. but not the axle housing....

    any thoughts, comments, etc??

    are there any axle builders on the net I could email and see what they say?

    thanks guys....

    What axle is it?

    No measurements for you, but if you look down the tubes, if its bent, you will see it.

    The way we check our housings we use for truss mockups is as follows

    Get a straight edge as long as your housing, we use a high quality 8 foot level.

    With the diff cover removed as well as the carrier, we place the level across the mounting surface of the cover. We measure several places along the tube to the level to check for front to back alignment.

    To check for up and down alignment put the level across corresponding points from side to side. Like the bottom of the C's or the ball joint and measure the same to check for up and down alignment.

    If your housing is bent it will be in the drivers' side tube, if it is more than a 1/4" out of line, chuck the housing and find another. They are readily available.
