I made the dumb move of not measuring the stock pinion angle of the driveshaft before changing the springs. Now I want to put a 1 piece d/s in the car and need to know what the angle should be to avoid vibration. Anyone have any idea?

I did not change the pinion angle, and the car runs perfectly smooth and vibe free all the way to redline in 5th gear.
sadil said:I already bought the dynotech shaft months back so the DSS is not an option. Everything I have read about pinion angles calls for the transmission and diff to be parallel. Do you guys concur? Of course this is only applicable to non CV shafts to ensure alignment. Therefore I think it is more important to align those two systems rather than aim for a specific angle. My uca is stock and my lcas are cortex, so poly bushings.
I'll report back when I get underneath the car. Thanks for the [email protected]
Justin said:This is what you would ideally set it to
~If all the control arms have Factory bushings: Set Pinion Angle 3 degrees to 4 degrees downward.
~If all the control arms have Poly bushings: Set Pinion Angle 2 1/2 degrees to 3 degrees downward.
~If all the control arms have Solid bushings: Set Pinion Angle 1 degrees to 1 ½ degrees downward.
I did mine from the flange. I think if you youtube search setting pinion angle you will see a video posted by cjpony parts they show you exactly where.Flyboygsxr said:My question is where did you measure the angle from? Did you use the flat surface in front of the diff?
