what about 2wd with hubs locked?

Do you have hubs?

Did it dent anything?

I dont see any dents

In 2 wheel with the hubs locked nothing happens

Yes i have locking hubs...

pretty far out on the axle, sounds more like a rock being thrown around somewhere, it gets louder and faster the faster i go if i go real slow theirs no noise....thanks for the help so far guys

Check your driveline to make sure you don't have a rock lodged somewhere. Also, I've dinged the "dust shield" on the pinion seal - it rubbed on the diff housing.

What about turning vs driving in straight line?
