DA and Ultegra provide a small black cogged plastic wheel to adjust preload with each crankset. Also this wheel is generally available on the spanner wrench end used to tightened the BB. If you didn't use one when you reinstalled your crank, then you have likely too much end play. Plastic wheel provides preload while you tighten both pinch bolts on the left crank arm.
