Pinion Angle Question

How do I know where to set the pinion angle when installing 4 link set up in my 57 gmc? I have no power train in the truck yet so there is no weight on the front but the 4 link brackets weld to the diff and don't want to have to cut and reweld them if the angle is wrong.

Re: Pinion Angle Question

Great diagram Dude! I always heard you need 1-3 degrees for the universals to work right, the diagram seems to confirm that. KG, isn't the 4 link adjustible so you can adjust the angle? I thought that was the whole purpose of the 4 link set up, to be able to optomize suspension settings??
