Vibration after spring change

What a difference a pinion angle makes. I just made a pack of washers with some electrical tape and stuck it under the rear of the axles spring pad to angle the front down and the noise was gone. I just went for a drive and I still hear a little something but it doesn't shake the car anymore. I'll be ordering some shims I guess and probably a new u-joint, I'm thinking mine may have worn to the old spring height and didn't like the change. I'm also going to be changing to a 8 1/4" someday so I might wait till then.

Thanks everyone for the help!
