Question, how do you set a pinion angle on irs?

Weren't you putting something together for us to check what our angles are at, and what they should be at? Like a quick How-To?!?!?

You dont set the pinion angle on an irs set up its static. I fixed my pinion angle at my trans x member by adding spacers 1/4 inch at all 4 points ..you can also adjust it with aftermarket motor mounts..

there is no chance you coincidentally lost a wheel weight?

Too many issues to do this, and too much time with doing tech. People just simply do not understand driveline working angles for the most part.

I help people out quite a bit though.

On BluBallz, I am running the pinion 1.8 degrees "down" in relation to the engine angle.

My engine angle is at 3.8 degrees "down"

Me pinion flange is at 2.0 degrees "up"

I set it with a combination of shims under just about every mounting point, front and rear. (front K-Member, engine height, trans crossmember, rear IRS cradle)

Here you can see the shims [MENTION=19179]BDMACH1[/MENTION]

Just an FYI, my car ended up needing the cradle shimmed down to get the pinion angle within the desired spec. @BMR Tech was a huge help in me getting the car sorted out. 95% of vibration issues are all gone, I'm in the process now of making some cradle shims to get the pinion angle exactly where we want it..
