As the title states, when coming to a stop and I hit a few repeated small bumps sometimes I feel a "clank" in the drive train (also felt through the shifter). Usually when this happens the ABS engages it's anti-lock system. The clank and ABS engagement definitely seem related. I am wondering if this is a transmission (ZF-6) or transfer case issue. I know on some vehicles, speed is calculated from the transfer case so I thought some "slop" in there was a possibility. I have no signs of pump rub or adverse sounds during normal driving.
