I drove it earlier, that's how I noticed the clicking. I noticed it leaving from a stop.

No vibrating at all though man.. even on the highway, I took it up to 100. There's just something not right. It's almost like they're not fully engaged. This is something new, could I have disconnected them too much when I dropped the subframe? The subframe was lowered all the way, once the rear 2 bolts were removed.
