Bent Rearend?

[HIVOLTG]

So got the rear end out of my truck tonight and it was looking funny to me...

I measured from the inside of the axle tubes to my floor and from the outside of the axle tubes down and they are different. My pumpkin is lower in the middle and got me thinking this must have bent from the accident?? Also the difference between the inside/outside is not the same on either side...

If anyone knows any different I would appreciate input, I would assume the rear end should be 100% straight?:shrug:

Also, I have been driving on the rear this way since June and always thought my rear tires looked slanted in...

Tire wear really isnt evident but the insides of the tires do look "squared off" or like they have an edge over being round
