What model is your drill and what Jacobs chuck did you use
Older 14.4v Power Plus Hammer Drill. 1/2-20 spindle. We've also had a few over the years at work as well, chucks replaced under warranty with the same loosening problems, especially when hammer drilling.
The jacobs chuck is an XRP 700 series, and the interesting thing about it, it has german/english for the open/close rather english/french that is so common around here. This chuck was around 40 bucks from the local Dewalt store. And when you lock it down, it stays locked down.
