Everything I have watched and read and experimented with so far, and since my vibrations are at low speeds I'm still of the opinion that they are a driveline angle vibration, not a driveshaft balancing, or alignment, or tire vibration. So in my next attempts to correct driveline angles, yes, I am currently sitting at a 2" lift, front and back.
I have Delta 3" arms. I have not done an alignment yet to see what my caster is. The last caster measurement was 3.4 degrees but that was at 2.5'' lift. I need to see what it is now that the front is 1/2" lower. Then I will move to Dobinsons rubber 2.5 degree bushings in my OEM arms. The reason for this and not the delta 2" arms is that Ive already had them, and also that all the delta arms ive used correct caster but are also longer. Now a longer arm should not affect vibes, but it is the only thing that has been consistent since the vibes started. So why not rule it in or out?
So first alignment.
Then 2.5 degree caster bushings on OEM arms.
