When I went to NTB a month ago, I asked them to align my car... When i came to pick it up they told me that my passenger rear control arm was bent. I didn't know to ask lower or upper because I'm still a car newb. Now I'm trying to replace it myself, but I don't know if it's the lower or the upper control arm. Is one or the other more likely to bend?

Any input is appreciated. Thanks

 

bump... anyone?

 

the upper is thiner metal but theres no way to be 100% sure. u should call them or somethign see if they have it in record or if they remember.
