Bending a rear axle housing or tube requires some extreme external force unless it was built that way at the factory!

Could this be bad bearings that cause this? When you are driving the wheels would want to pull forward and so when they drive it up on the alignment rack it might have them toed forward.

I asked the guy that. Im like, I think I would have known if I bent the axle at some point so unless the previous owner did something I dont believe it.

Not mention as Gordon stated all the negative or adverse effects it would have on the carrier components!

When you pull a vehicle onto an alignment rack, all the tires are placed onto pads that when you pull the locking pins out of the pads, which set on roller bearings, they allow the entire suspension to relax so nothing is under any stress during the alignment measuring and adjustment process.
I have performed untold number of alignments on many types of vehicles over the years and have never encountered a negative toe between just the two rear wheels on a solid tube type rear axle unless it was involved in a wreck or accident! If the rear axle was bent due to an accident, it required replacing the entire assembly! There was no straightening it!
On an independent rear suspension you can adjust toe-in, but on a solid rear axle about the only thing you can do is to make sure the rear axle assembly is aligned parallel to the front tires so they all track together in a straight line.

If an axle bearing was worn enough to cause what you described, it would be extremely noisy and leaking oil profusely as it would have already wiped the axle seal. Not to mention as others stated all the negative or adverse effects it would have on the carrier components!

Another possibility would be a bent wheel, but I would hope your alignment person checked wheel run-out?
My guess would be equipment malfunction giving a false reading or the operator is not competent? (hate to say this not knowing the operator! )
If it were mine, I would get a second opinion from a different alignment shop!

Keep us posted, I am most interested in the outcome!!!!

That doesn't seem like enough to worry about.
And there is nothing you can do to change it.
About the only thing you can do is replace the lower control arms and convince yourself that its all better.

Seriously, are you worried about that? I'll bet that's way less than the margin of repeatable error of either machine or operator, and definitely beyond the capability of both together.

Not only would a different shop get a different reading, you couldn't even take it back to the same operator at the same shop and get the same result without them faking it.

Sorry, changing the control arms on the rear will NOT change rear axle toe from left to right wheel, only tracking as compared to front wheels in parallel straight lines!
0.039 is 1/16 over 3/8 of an inch or 25/64
Still not sure how a solid straight rear axle could have a lot of negative toe unless something is bent!

But if you are not having a problem with rear tire wear indicative of negative toe, I would simply ignore it or better yet if you are concerned, take it to a another good alighment shop and see if they are able to repeat the readings, but just don't tell them about the first readings you got. Sort of like a blind test!

No it would only straighten the axle with respect to the body, and make the toe even on each side(.19/.19)

I think i am gunna just ignore it. I've been driving it like this for a long time I assume and I am not sure that the rear has anything to do with the tire wear.
