Default Needing Help Narrowing Down Damaged Suspension Components After Curb Impact

I hit a curb head on moving about 20 mph, I have inspected my suspension components and the most apparent issue that I see is leaking at the transverse link. I will be ordering aluminum lower control arms with transverse links. I understand my crossmember or strut could be bent along with damage to endlinks, balljoints, tie rods, tie rod ends etc.

My passenger side was the affected wheel. The wheel is pushed toward the back of my fender roughly 1 inch.

When turning left, my entire wheel rotates out/forward toward the front fender.

When turning right, my entire wheel rotates in/back contacting my mudflap/back of wheel well.

Could this movement be entirely related to a bent lower control arm (No visible damage aside from transverse link.) Or is there something else specifically that would allow this rotational forward/back movement specifically?

Thank You very much in advance for any insight!

What I think you are calling the transverse link (the one that goes front to back) is what should be centering the wheel in the wheel-well. So if the wheel is moving front to back then you have an issue with that link...OR the strut has been damaged in a way that the strut is moving the whole assembly back and forth.

The lateral links should only affect track width and camber/toe of the wheels.

A transverse link IS the control arm.

There is only one control arm (transverse link) up front in either side. No upper or lower, just a control arm or call it a transverse link. There is also a front transverse link bushing and a rear transverse link bushing.

OP, at 20 mph you probably bent a bunch of stuff. Detailed pictures would help. Or just take it to a shop that is very familiar with Subaru.

You may have damaged the knuckle and wheel bearings as well.

Sorry for the terminology differences. When saying transverse link, I am indeed talking about the transverse link bushing. I understand that there is only one front control arm on our cars. I'm simply using the general term "Lower Control Arm"

I should have titled this thread more appropriately, I am not looking to narrow down damaged suspension components. I am only looking for the cause of this front/back movement of the wheel within the wheel well with steering input.

I am wondering if the transverse link bushing could be the main cause of this movement, or if this movement is standard and simply seems exaggerated because of the location of the wheel toward the back of the wheel well.

The picture is not working for me.

Anyway, with the way you described how the wheel sits, you most likely bent the control arm and not the rear bushing. The bushing may have been damaged too though. If it's bad enough you may have tweaked the crossmember as well.

Not to mention:
Tie rods.
Ball joints
Knuckle
Wheel bearing
Strut
Wheel
Sway bar
Sway bar end link

But you can assume the control arm is shot.

Lastly, if you can't get it aligned properly then you know something else is bent. Don't "fix the problem" with aftermarket camber bolts or other crap. Get it right with good straight components!!!!!

Good luck

I would also take a look at inner tie end rod and if it's damaged I would check steering rack for damage.

Thank you for the insight everyone!

So far I have replaced control arms, endlinks, ball joints.

Things seem to be back where they should be. I will be replacing my wheel bearings shortly as they do have a bit of play, and will also be aligning the car.
