Car won’t go straight after crash and replaced arms
Hey I recently had my back end slip on a wide turn and my car hit the curb and the wheel was crooked. i replaced the toe control arm and lower control arm and and the spring bucket. The car can’t drive straight unless the wheels is turned 45 degrees to the right and it still doesn’t drive straight. I replaced the bent pieces and i don’t know what the problem is now I want to take it to an alignment shop but I don’t know if they can do much to rear alignment. I’m gonna drop pictures. But please help and drop anything that it might be. This is what happened Next three are after I replaced the pieces
An alignment shop can determine if your alignment can be corrected...............or if there is any frame damage. There may be more damage to parts other than what you have replaced.

what other damages could there be i hope it’s not the whole cross member

The Z's rear aluminum suspension cradle may have been bent or distorted by the shunt. That was a serious impact from the pic, and an alignment shop could help pinpoint where the damage lies.
As soon as I saw the initial photo, betting on cross member. Tried stress-testing it? Placing a jack under the wheel and apply lift and see if there's any play or noises coming from that general area. What about axles? Wheel bearing good? Strut good? etc

These are the pieces I replaced I hope it’s just mis properly aligned

what can I look at if i get under the car to see if the cross member is messed up

It is difficult to say without physically looking at the car. Do you have insurance? I would suggest taking your Z to a body or frame shop and have it inspected. The rear sub frame could be damaged.

Ya i do but it’s only liability. I will after I go to the alignment shop if they can’t do anything
That wheel (rim) is probably bent, looking at that hit. Given that alignment shops work off the wheel rims and not the hubs, I would expect any alignment you get could be way out given a 180deg rotation of the wheel.
Get the tire dismounted and check the wheel for straightness on a known-flat surface before the alignment.
Our cars are pretty rear-toe sensitive, so in addition to saving the $ from a bad alignment, you might save the back of your car from another curb.
Good luck, glad you’re safe and it’s just the car.
Just my opinion, but based on the photos, the rear subframe (also referred to as cross-member) is bent. This will throw the rear suspension geometry off entirely and it won't just be limited to one side. A whole new subframe will be needed imo. Even then, there's no guarantee that unibody frame damage isn't a factor. I'm honestly shocked the wheel didn't crack from the hit.

i mean the other side is ok though it still has spec alignment and ya the rim didn’t crack cause i was going about 15 or something mph.
