PINION ANGLE

[mustangspartan]

Ok lowered the beast and got the upr adjustable uppers for the rear. Im getting how to go and adjust it.. Here is the deal.. Dont have access to a hoist that will compress the suspension. I have jacked it up and let it rest on the rear axels to get a compressed suspension feel. My issue it that most all of the write ups ive seen so far are only if it is all four.. Anyone ever do this with it jacked up rear only..

I found looking at the crank pulley and getting a reading on that then off the face of the pinion has gotten me the closest so far but still having a rear feeling vibration.. I have spun the driveshaft to basically every available setting but still nothing.

I've had almost the same issue when I installed torque arm. Car started to vibrate at highway speed, which sucked big time, since I drive the car a lot. I've checked the pinion angle every which way, and I still can't find the problem. My next step is replacing the axle shafts, because one of them is fairly bent. Think outside of the box. What else can transfer vibration that you did not feel through softer bushings?

Next is aluminum driveshaft new engine mounts and also balancer.. I have another thread open on the vibration issue but need to find if someone has a idea of how to do the angle with only two jacks under the rear
