The front axle yoke was the big problem, as currently it is available only direct from AAM. Fortunately, JE Reel moves enough of these style driveshafts to be on the short list of companies that AAM will sell to direct. If your local driveshaft shop can’t get the yoke, you can also pick it up from your local dealership (PN 68067348AA). We ended up with four different U-joints between our front and rear drivelines, which bothers us because we need to carry four different U-joints as spares. However, it didn’t bother us enough to spend the big dollars for all new drivelines to match U-joint sizes.
