I dunno. With those things I'd never say never, but not likely it's the pump. If a pump(s) got to cavitating it would scream, but not really growl. I'm just fresh after changing the U-joints on one side of the front axle, and the noise that came from that under load before it went to pieces was best described as a deep growl. That's why I'd suggest looking at the front more... and it was felt right up to and through the foot boards.
Beyond that I'd ask if there's any trouble shifting it? What about the transfer case?
Again, probably 75% of the problems we've had with our 3930 have been FWD related. I've lost count of how many times the hubs have been apart for rings and planet gears. Also, a drive shaft problem will become much more evident at road speed than at low speeds. It will shake badly...
Hydraulics.... depends on how you have it plumbed. IF it's a dual pump model, the speed is decent, but by no means fast. If you have a loader joystick plugged into a remote, then you have a tandem center valve most likely, and you won't really get simultaneous function from that valve. If you operate the loader strictly off the remotes you should get some degree of simultaneous function from those valves if you set the flow control down somewhat. They are closed center valves... but I wouldn't expect too much if you're used to the performance of an industrial. We've got a larger pump on ours and squeeze a couple more gpm from it, but it's still not fast. It has plenty of power, but slow.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
