i have a 78 k10 i have a really bad vibration goin down the road around 45 its so bad that some times i have to pull over and then go on down the road i replaced the tie rod ends and had a front end alighnment done i now some trucks do this with worn tires but i got a set of thornbirds with half tread ive pretty much tried everything i can think of does anyone know what this could be the tires? ball joints? i really dont know what the hell to try i have noticed that my transfer case shifter also moves a lil bit when this occurs but i dont think mounts would cause front end problems would they?
