Re: front noise, road noise.. cant pinpoint
Could be the CV joint yes. To rule out a problem with the propeller shaft joints, you could remove the front propeller shaft and see if that makes any difference. If you would do so, mark the joint position with the flanges before removal, so that you can put it back in the exact same position.
The diff could make noise, but that should not change when making turns.
What could happen as well is the chain inside the T-case which skips teeth. That can happen when the chain is stretched too much, but that would be the last thing to check.
