Hello, I have an 01 24v 4x4. I took it on a 200 miles round trip last week. Within 10 miles of the destination I heard a noticeable loud squeal/screech intermediately at around 50 mph. I thought is could be my front pumpkin running low due to a drivers side leak, filled it up and drove home. On way home the noise was still in and out, towards the end it started to become more constant but only above 2-3rd gear. Now when I drive its is constant above 2nd gear at pretty much any speed. It sounds like it could be from the transmission but I was thinking more wheel bearing/ joint. I will jack up rear and update tomorrow. 
 
	What I have done
 
	New driver/passenger side wheel bearings
 
	New both side u joints
 
	New axel seals each side on front axle
 
	Took of front drive shaft and drove with it off
 
	Greased everything
 
	New atf in transfer case
 
	New front brakes/aren't sticking
 
	Flushed power steering and refilled/bleed
 
	 
 
	Noise is metal on metal(sounds like) rotating above 20 mph. With windows down it sounds like drivers side wheel bearing. Also could be transmission since I hear it through other window.
 
	Hope someone has some input on this. Dont want to pull nv5600 if i dont have to.
