Bad noises

So i successfully did the mono leaf mod, and loved it from day one, but that was two weeks ago, now i have a problem. As I drive, somewhere in the drivetrain after the transmission is making a clicking/grinding sound under acceleration, or even while at cruising speed on the highway.

Has anyone else experienced this problem? if so any help would be greatly appreciated

you U joints sh!t the bed... better have them replaced before it pukes out, its not fun when that happens
