Re: rear end pinion angle issues

The pinion nose of the axle moves up and down quite a bit under acceleration and deceleration, due to leaf spring wind up.

I had an opportunity to drive my '87 pickup without the box on it and was surprised at how much motion there was going on back there.

Assuming that the perches are welded to the tube it could very well be normal.
