I own a 2004 nissan maxima SE. now i've had this problem for months now and i can't seem to fix it. when im driving and speed is at 50 through 70 the steering wheel shaking/vibrating bad. now i have gotten a wheel balance, a tire roation. and it didnt seem to work. now i took it to a shop and tried getting wheel alignment. explained my problem and told him i wanted a wheel alignment. came back a couple of hrs later and told me that it has something to do with the wheels it was all unbalance. he also said i didnt seem to need a wheel alignment. and basically wasted my time. now i don't really know what to do. is there anybody that cangive me a suggestion..
