bent rearend?

I posted on this a long time ago but haven't ever fixed it yet, but i was wondering, if the bearings on the side of the diff. carrier were severely wore or not set up right, could it **** the axle shafts at an angle and make the tires lean in at top like the housing was bent?

i am no expert but...

this is how i see it: the brakes are bolted to the housing and the wheel is bolted to the brakes, and the axle just goes through the wheel and brakes and housing. For a wheel to be off straight i would think that there must be something really wrong. how far off is it? Or the rim might be bent? When, if you can, jack up the rear and try to spin the tire and see if it turns on the same axes or if it wables. If it kinda wables then i would think that the rim is just bent. Good luck. And if someone knows more about this please say other wise.

If a bearing was that bad it would be leaking lub out the axle seal. You would also be able to move the axle up and down.

Have you over loaded the axle with a goose neck trailer and bend the axle tube?

No.

But a broken rear leaf spring will cause a vehicle to "dog track." When the rear leaf spring breaks, the rear axle will shift to one side.

Ever follow someone while driving and notice you can see all four tires instead of just the two rear ones? A rear leaf spring has broken, this causes the axle to shift, and now, not only are the rear tires visable, but so are the fronts. This scenario is known as dog tracking.

i've noticed dog tracking, yes, and no the wheels are not bent, they don't wobble, my leafs are wore out on one side causing it to sag on the p-side, but that would cause them to drive in one direction wouldn't it? instead of both tires leaning in at the top? I guess it is prob bent but more feedback is appreciated.

I'm inclined to go along with blue68f100. I've seen trailer axles bend like that from being overloaded, so, I see no reason for a rear end to be any different. Maybe someone hauled something heavier than the axle was intended to handle. If that's the case, you can have it straightened, but you might be better off to hit a u-pull-it and replace it.
Best of luck to you.

Put it on a computerized four wheel alignment machine and that will tell you for sure if it's bent.
