Hi, Today I installed a racer tech 2" lift. The lift went really good and was around 2 hrs to bolt it up. How ever in doing this I noticed the rear end was out by spinning the wheels. I let the wheels spin well the car was jacked at a few hun RPM and could see the dif was out of balance or some thing. The rzr drives fine on the road up to 60 km then it shakes. How can I find out if my frame is bent?
