ya at first i thought i bent my frame. i took it to the align shop and we gave it a thorough look, everything seems to be fine...no signs of stress, bends, or anything dangerous. the tech there did play w/ the lower ball joints and there was very little play and he told me the same thing as you guys, even the smallest play was critical. he told me everything i needed and through them w/ labor i was looking at 1700 bucks. so i ebayed what i needed (upper control arms w/ ball joints and lower ball joints) he said that a press would be needed for the lower ball joints but i found some joints that will already just mount onto the lower control arm.
besides the tech at the shop my tuner buddy looked at it also. he also thought that it was odd having diff sizes from left to right but that everything looks riight.
i will post up pics of the right and left control arms on my car and then the ones i ordered later today or tomorrow. the weird thing is on my car they match the ones i bought, but i will def post these asap...and if it doesn't work out i would like to take you up on your friends parts, thanks guys
