That for sure looks like wheels rubbing, he’s talking wheel offset. You could get some 1/4” slip on spacers if you have room between the tire and fender
That would only cause rubbing noises, and probably only rubs at full lock when you're turning in parking lots and such. Look elsewhere for your rattle. Again, as I've mentioned on your other posts regarding the issue, if you're running the ball joints that came with the DJM arms, you need to change those now. They're junk. They last long enough so they're out of the 90 day warranty and that's it. Use an OEM ball joint for your truck.
