im putting a UMI torque arm on my TA and was wondering what angle my driveshaft should be at and all that jazz..any help would be awesome!

1 to 1.5 degree difference than the shafts angle at the pinion in the negative side.

So if the shaft is at 0.0 you want the pin pointing down 1.5 degrees.

Auto or manual? With an automatic transmission you run just a little less down angle than a manual. Negative 1.5 is generally the setup for an auto equipped car.

No a popping banging noise is not a angle issue

I had the same problem when I installed mine, I had a tunnel mounted arm on my 9" axle, turned out I had clearance issues in the tunnel. I went back to a transmission crossmember mounted arm and a new trans bushing and it went away for me.
