Rear alignment

[BackRoadsAreBetter]

I have a 2013 that has an issue with the alignment in the rear.
Pretty sure a railroad crossing bent the housing or hub flange but I want to figure out how to go about finding what the issue is before just throwing another housing at it.

The toe is out on both sides, as if the rear axle is at a slight angle, but is out a bit more on one side. So slightly psoitive on one side and negative on the other.

Any advise is welcome.
I can post a photo of the last alignment readout if it helps

I would check the rear control arm bushings and also look at the arms themselves to make sure they are straight and not bent.

Thanks for the input.
Do the control arm need to be removed or can they be inspected on the vehicle?
