What did you do on your 70 series today? (28 Viewers)

In the quest to track down my 65mph+ vibration, I just put in a new pinion flange. Looking forward to test driving it tonight.

I have been chasing the same. Only things not been replaced are the wheels, which might be happening soon.

Ya’ll got caster shims?

Yes I do, installed along with the Dobinson suspension. In my case I'm pretty sure its coming from the rear end. It's in the driveline, not the tcase or driveshaft or apparentlybtye dang pinion flange. I have new wheels and newish tires, balanced and rotated. Out-of-balance drums? Pinion bearing? Rear wheel bearing? I can't feel any play but process of elimination is sending me there.
