Default Whirring noise......?....driveshaft...?
OK.....so i got the driveshaft install all done and back on the road, great! But now there seems to be a shirring noise, almost like a whining, kinda like a gear driven HP motor, coming from under the Jeep. It gets louder with the speed of the Jeep, and eventually it's drowned out by the noise of the tires, and soft top.

Could i have tightened the nut that holds the yokes on too tight? Maybe slightly crushing the bearings?

Did you retorque the pinion nut to 150 foot pounds. And you need to check pinion preload as you do this.
