Ok, so maybe I'm just a pampered princess who got used to driving a Lexus (at least that's what my wife told me), but I just bought my first 4runner (99 limited 2wd), and noticed it has a very stiff ride. I can feel every bump in the road. Is this normal, it being a truck? Or do I need new struts? 150k, and the struts look to be the original.
