    Im pretty sure the knuckles are all the same, its the spindles and hubs that are different.

    Let me see if I can find a pic of the flattop knuckles. Basically they are just what theyre called, theyre knuckles with flat tops. /forums/images/icons/blush.gif

    yet they wiol work on any dana 44 housing right ? different balljoints, or ? how does flat top give any clearance for offroaders ? being that they are flat does that mean they arent as tall ofg a knuckle as ones that are not flat topped ?

    thanks

    I think the balljoints would all be the same. As far as the flattop knuckles, they are needed to use crossover steering. The steering arms locate on top of the knuckle like the stock arm, but theyre a different design. I dont know the specifics though.

    The thing to watch out for with swapping the knuckles is the tie-rod position where it bolts to the knuckle holes.

    The older ('76 and older) have tie rods mounting on the top part of the knuckle and the tie rod therefore "bends" down a little bit to clear the front springs.

    The newer ('77 on up) have tie rods mounting on the bottom side of the knuckles.

    If you took the knuckles off and laid them side by side, you will see where the casting is different a different height than the other knuckle.

    The general rule to use when swapping the knuckles is to use the same year tie rod as the knuckle being swapped in. /forums/images/icons/wink.gif
