Carrier bearing noise

[65Gregg]

I am getting noise from my carrier bearing. I recently did a 4/5 static drop and as soon as I rolled down the driveway I could hear a high pitched noise. Lifted the truck up on jack stands and turned the rear wheels and determined it was the carrier bearing. I replaced the noisy culprit and still have the same problem just a different noise. The front part of the drive shaft has 1 degree of angle, higher in the rear. The rear has 3 1/2 degrees of angle, it is higher in the rear also. I have placed my angle finder on the driveway and it has less than 1 degree of slope. Does anyone have suggestions, thoughts, etc on how much i need to shim the pinon angle to correct this issuue. Thanks.
