189k on the clock. Have owned for about 18 months. Previously wrecked, drivers side door & front fender replaced by owner.[not professional] Car drives horribly. Recently replaced wheel bearing assemblies [front] & tie rods + 4 wheel alignment. That is all the shop found wrong. Car is very "darty" in steering, to the point of being scary. Struts have not been changed out yet, probably still factory. Could this be causing my problem? Im 57 yrs old & this seems to be the worst engineered car I have ever owned. It seems like GM simply put a v-8 in a car set up for a v-6. please recommend struts as all I have checked on are the Monroes for Impala w/ 18" wheels. Thanks, Steve
