Did the clocking no difference. Never did the balance that might have helped? So returned it for full credit and put back the 2 piece after rebuilding the CMB and replacing the tranny rear isolater support, tranny sags with age and not very noticeable with eyes. Had normal ride before and after with the 2 piece. The Nissan engineers realized the harmonics in the drive line was an issue and they fixed it with the 2 piece and CMB support.
If doing a 2 piece DS CMB rebuild make sure all parts are indexed before pulling apart, they have to go back the same way.
