Piggyback is when the balancer bolts to the pulley. If it is wobbling, you must try and find out why or else it could strand you by throwing a belt. Check the bolts that hold them together. The pics you saw...they spent a little more dough on pullies that have the balancer built into the underdrive pulley. It is one unit. Those are better.

I would just get rid of the bbk's and get steedas. Piggyback pullies were never all that good to begin with.

The wobble could be a problem, so please check it and maybe take the time to reinstall. However, I wouldn't get rid of the BBK pullies just yet. I have a 2002 GT, with 115,000 miles and about 90,000 miles are with BBK underdrive pullies and no problems so far.

We had a BBK setup like this on my dad's Bullitt. Get rid of that POS. It was making the engine run rough and ping. We finally changed it out of another unit that was a full replacement underdrive pully/ballancer that did not piggy back, I think it was a March. After we switched it out the engine ran fine again.
