Reason I asked it if was on sharp turns only, is that two "common" things can make growling, bumping noises when doing tight turns.
The larger than stock front tires will rub the radius arms is the most likely, but do not usually make a popping sound in a high-pitch unless they are very aggressive mud tires. Yours don't look like that, but they may still be rubbing.
The other is that the rear differential may be a limited-slip type and is grumbling from not having the proper lubrication.
Of course, other things that can make noises up front are:
1. steel wheels flexing, or worse that have cracks.
2. Loose or failing wheel bearings.
3. Brake pads loose in the calipers (rare to have drum brakes make noise, but a loose spring or something could make that noise I suppose).
4. Locking mechanism in one or both of the hubs half-engaged, or broken.
5. Axleshaft u-joints if the hubs are locked, or half-locked.
6. Driveshaft u-joints at either end.
7. Other stuff...;D
