Questions about wheel speed sensor wire and CV axle after wreck

Hoping to get more traction here than I did on reddit.

Hello, first off this is a 2008 toyota prius. I fell asleep at the wheel one morning, woke up and barely hit a concrete divider. As in if i were 3 inches over i would have missed it. I had to replace most of the suspension components in the front driver side including the subframe. The wheel hit the divider and bent the control arm, sway bar link, shock and conpletely broke the axle, tie rod is fine.Everything went smooth except I feel like my cv axle may be too short.

When the axle nut is tightened it makes this horrible noise close to the cup thats in the transmission and the wheel has a hard time turning. When the axle nut is tightened it pulls the axle out of the cup if that makes sense, and I feel like the components inside the cup are kinda disengaging. If i loosen the axle nut, the noise goes away. This is an aftermarket trakmotive cv axle. Going to try picking one up from napa to see if that fixes it, but does anyone have any ideas? What are the odds the force of this wreck damaged the transmission? The shaft completely broke out of the cup, only the cup remained in the transmission. I included a picture without the wheel before the repair aswell.

Second question is this wheel speed sensor wire. I replaced the wheel speed sensor but after the connection before the fusebox, the wire is pretty damaged. My scanner says wheel speed sensor is still the fault. The other codes im pretty sure are because the battery was super low. No check engine light but abs and some others. In the image, the copper piece that I have circled, does that need to be connected the whole way through the wire? I've never seen inside an abs harness before. What about this wire would cause me to still have these lights, or perhaps something I haven't considered.
