That definitely bent your frame. They measure the deflection using computers and special tools. You probably wont tell with the naked eye unless you strip the whole car and measure.

Theres no way you can say that definitely bent the frame. I've seen cars that have been in multiple fender-benders, gone off-roading and curb-checking and were still straight.

I'm sure your alignment is out of whack, so I'd take it to an alignment shop first, and if they can get it into spec and the car drives straight, I'd say you're in the clear. :edit: If the car still isn't quite right, or if they can't get it into spec, then its time to make a trip to the body shop :hs:

sure, they probably looked straight and drove like normal, but it doesnt change the fact that the frame was bent. you have to remember that the frame is made of reclangular sections, not trusses. Most of us probably drive cars with frames that are less than perfect.

My friend hit a curb and he took his car to the shop afterwards. He didnt hit it hard, he only had a one or two inch mark on his rim, in performance, you wouldnt tell a difference. But they checked his frame and it was off by an inch and half. If you shred your tires when jumping a curb, theres a very high chance of having a bent frame. However the frame is the last thing id be worried about, he should check his axles and drivetrain, control arms, etc.

Think about all the cushion thats built in before the frame factors in. Tire deflection and breakage (if they popped, I'm sure they moved quite a lot before doing so, dissapating the force of the impact), and several soft rubber bushings, and then suspension arms which are designed to bend before breaking. Sure, if you curb check hard enough, it'll definitely bend the frame, but you essentially have to knock the wheel hard enough to move it a couple inches or more inboard before that will happen.

That said, if the alignment and driving characteristics are unaffected, the frame for all intents and purposes isn't bent. My guess is that the body shop was trying to make some dough.

I agree, but the shop diagnosed it w/a computer which basically mapped out his whole frame and stuff. so, his frame was infact bent, however I remember now that he was telling me that it was a matter of sheer coincidence that he hit the curb in such a spot on his wheel as to not cause any damage to the axels and all the suspension components.

Because I remember another case where another guy broke his wheels out and he was very close to the curb, and his rear wheel went sideways into the curb. Now I remember looking at the wheel and I could actually see, even from afar that the wheel was sitting at an angle. Needless to say the car would not drive and it had to be towed, he basically bent his rear axle.

Thats actually a pretty sad story, because the car was a brand new M/B CL55, and it was a valet parking attendant who did that to it.

line 7 you really don't know much about collision work do you? Hitting curbs and bending uni body, yeah right, take this from my experience in the automotive field, your suspension is designed to give espically since last time i checked they had rubber bushings in them. I would take it to a good alignment shop and have a four wheel alignment performed, and most like your friends car who's frame was off an inch and a half probally was wrecked at one oint before that and never repaired right, but hey i could be wrong, its not like I do alignments and turn wrenches for a living.

heh, what do you know maybe i was right. j/k.

sorry to hear that man, you should deffinitely have a specialist look at it. Did the guys who did your alignment say what the problem might be?
