Pretty sure my pinion angle on my front 3rd is way off. When I turn the tires squeel and they dont look straight up and down when I have it fully turned. Im planning on moving my axle forward by drilling my spring perches and want to address my angle issue at the same time. I know moving it forward will only make the angle worse. What should the angle be and how do I measure it. I have one of those inclometers (or whatever theyre called) just dont know where to put it on the axle to read it correctly. thanks
