I have a 1998 Chevy blazer with the zr2 off-road suspension and whenever i ride over the smallest of bumps it hits real hard, i mean you can feel ever bump you run over in my vehicle. Also sometimes its hard to keep it steering straight.. I was wondering if it could be the struts/shocks or if its because of the off-road suspension, which i don't think it would be.. I'm trying to sell this vehicle and i don't want to sell someone a lemon... Any help would be appreciated, thank you!!!
