When I get up to about 60-65 there is a slight vibration in the steering wheel and car. I was told I need to replace the control arm bushings (when do they not need to be, lol), but I wasn't sure if that was the reason. Could it just be the alignment? Any help would be great. Also, going on a road trip soon, from Memphis to St Louis, bout 280 miles each way, how bad would it be to drive it there and back like this? Thanks.
