I've noticed my blazer frame has a lot of flex when driven on unlevel roads. It is even noticeable when just turning the tires. A lot of that flex is transferred to the body, affecting the doors, I even heard the dashboard creaking the last time I went off road. Has anyone welded the front crossmember to the frame? Right now it is only bolted. I dont see any reason for allowing removal of the crossmember, so I should be able to weld it, right?
