I was just under my car to replace a creaky ball joint and remove lowering springs. After reassembly, the car sports a slow, heavy vibration. The vibration is with wheel speed, and is most intense above 35 under acceleration, but it is also present under decel. It is not present in transition, i.e. between accel and decel. It is not present at all at speed in neutral. Left turns do not affect tne vibration, right turns magnify it significantly. I cant find anything loose/improperly torqued(not to say there isn't).

All I can find is a slightly (and I mean SLIGHTLY) jiggly drivers half shaft...
