Curb slam damage to the wheel?

There can be multiple damaged items if you have a curb strike. Control arms, Tie rod ends and steering knuckles the wheel and tire being the most common damaged parts, but I have seen subframe mounts, wheel bearings and even the unibody get damaged from very hard hits. It takes a close examination of the vehicle to find the damage. I generally start with a visual inspection of the chassis looking for things that are bent or that look bent, then the tires for bulges or bubbles or belt damage and wheels for bent or cracked areas. Then onto the alignment rack to see how far out it is before any repairs as that could also show that even though you may be sure you only hit with say, the right rear, it may have hit the front and you didn't notice, or you think you hit with the steering wheel straight but it was turned just enough that it stressed the inner tie rod. Then you make a list of what needs repair or replacement.
Now if it was only the control arm and the rest is okay (although if it bent the control arm, I would seriously check the tire and rim as it takes a lot to bend parts) it would be a replacement of the arm and an alignment.
The images are the front and rear suspension with the most commonly bent items circled. However, being this is AWD you will need to check that the impact didn't damage the axle shafts or joints as well. Especially if it was the rear suspension, they seem to be fragile.

Hi,

I attached a pic below and highlighted what I believe you are referring to. Please confirm.

If that needed to be disconnected for the wheel to sit straight, I would remove it and inspect it to see if there is damage. Certainly, it could be bent, but check what it attaches to on both ends to make sure the problem isn't something different.

Let me know.

See pic below.

If the part, Joe highlighted has to be disconnected it's most likely going to be bent ears where in mounts on the subframe. It could be just the arms, but I have seen the subframe bend as well. You will want to look at the rear axle assembly for signs of impact damage, they only compress a small amount and if the inner joint bottomed out it may have damaged the rear differential as well.

That is the lower control arm. If it bent the upper and the lower control arms you will want to get it on an alignment rack and check to see if the rear subframe shifted as well as the rear alignment. Those parts take a lot of force to bend.
