pinion angle

How do you find the correct pinion angle? and how do you know its the correct angle. I know there is an angle finder that you can find at the home depot, but is there a formula for diffrent size lifts or a certain degree for the diffrent size lifts. What is the number that you need to get to have that correct angle?

If I were to put a coil spacer under the 4.5 coils would it change the angle in a major way?

Just curious because I have a 4.5 re sa lift and have a slight vibe in the range of 30-40 mph. I dont have a sye/cv but want one. I also want to put the acos coil spacers in. Should I put the coil spacer in before I get the sye/cv or does it matter?


Thanks again

So here is a link to Tom Woods website that tells about angles. Clicky. Personally I would have done the SYE/CV when I did the 4.5 SF and I would def. not go higher before I got that done. It may not bother you much but you are causing undue stress on a lot of parts if you just leave a vibration and it will eventually take its toll.

And to actually set the angle on the pinion/driveshaft you have to lengthen/shorten the upper control arms to set it. Hope that helps.
