Curb Damage

I hit a curb with my driver side rear wheel going about 45mph. Now it is more bouncy, sits lower, and has more negative camber than the passenger side. I changed the strut but the ride quality is still the same. Any ideas or suggestions on what I could/should do?

Yeah, stop hitting curbs.










Then, I think you may have to replace the hub.. Or just the whole axle if the damage is severe enough. Your camber arms could be bent which is maybe why your camber is off.. Also make sure you didn't crack/bend your rims (I'm assuming you did this already), that would be bad too. And then get an alignment.

You need to visit an independent brake/alignment shop to have your suspension checked out and get an alignment. I can guarantee they'll find areas of your suspension bent or broken! I'd also be concerned about the wheel/tire taking that kinda hit!

Yeah I inspected the the wheel/tire and they were ok but I replaced my tire anyway due to low threads.

I put the rear on jack stands, removed both rear wheels, and examined the two but I couldn't find any differences. How would I be able to tell if the axle was bent?

Honestly my man, it can be quite a few things. The suspension set-up in cars involve several different components. When you damage them by hitting things, it can be half a dozen things or just one. You won't know without getting under there and inspecting it, and you would need to know what to look for.

Just based on the symptoms you're describing, the wobbling is likely caused by: a damaged wheel hub/bearing, bent wheels, or damaged control arms. Since you say the wheels are fine and you've replaced the tires and balanced it, I'd lean toward the damaged wheel hub/bearing and/or control arm. If you're changing out the wheel bearing, you can easily check the axle by pulling it out and inspecting it. I doubt it's that though, because usually those just snap if you hit them hard enough and you WOULD know.

There's also the various arms/rods in the rear that could also be damaged. That could be causing the camber issues (damaged control arms can also do that). If you're not sure what to look for or how to diagnose the problem, take it to a knowledgeable shop (that specializes in suspension) and they can tell you exactly what you need to do. Otherwise you're just gonna be throwing parts and money at it hoping you catch the right thing.

Almost bet your wheel bearing is or will fail along with the hub.
