One-Piece Propeller Shaft
WARNING: This page is about a different car, the 2003 GMC Sonoma, 2003 GMC Jimmy, 2003 Chevrolet S10 Pickup, and 2003 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.
An out-of-phase one-piece propeller shaft is very unusual. If it has been determined that the shaft is out of phase as a result of performing the Propeller Shaft Phasing Inspection, then the end yokes are welded on in the wrong position, or the shaft is damaged due to twisting and the propeller shaft requires replacement.
