Pinion angle

pinion angle enough to cause a vibration. On page 4-24 of the service manual it describes rotating the rear shaft 4 splines to the left side of the vehicle. Model CE31403 rotates only two splines to the left. That phases the rear shaft to the front shaft regardless of the pinion yoke position. You should have both front and rear shafts with the (preferably new) carrier bearing balanced assembled together with new u-joints at a DS shop.

What service manual are you referring to? I have the 1970 service book and don't see what you are referring to.
