Your saying carrier bearing bracket? Pls explain more. The one on front where connect the trans? Delete the carrier bearing bracket? Spacer under tranny. How you do that and where get it if I need it? But cant figure without tell me how to correct measure.

Now get the angle of the driveshaft. This will tell us the angle of the driveshaft relative to the pinion. If your truck under load has enough axle wrap to put the pinion dead parallel with the driveshaft, you risk having a vibration.
