Strange noise and thump on the drivers side when going from 15-25.

Boy are you being lied to! ABS systems dont have anything to do with making thumps. It doe's sound like you have a problem with your tire. Some tires come apart from the inside out. Run your hand over the flat part of the tire and feel for a high spot. Or, put your spare tire on that side to eliminate that problem. When in doubt, take it in to an auto repair shop. Goodluck
