Whining noise from front end. starts at 5mph and

One wheel turning faster than the other is normal if both wheels are off the ground. If one wheel is dragging when the other wheel is on the ground, it could be brakes or a wheel hub bearing.
Usually if the noise happens on right turns, the left hub bearing is failing, and vice versa.

could be a wheel bearing jack the side with the noise & spin the wheel

Is it a "wine" noise that gets louder when you rev it up? Sounds like an idler pulley. Is it a 3.3L motor?

have you looked at the tires- if they are wore down the wear bars-little bands of rubber that cross the grooves in tread will be exposed and the noise is your warning to get new tires soon

this sounds like a hub bearing, to determine which one it is when your driving and you here the noise turn the steering wheel slightly left and then slightly right, the noise should get louder or lighter. If louder on right turn then it would be left bearing is bad because your putting more weight on the left side

sheck the power steering pump

Check the condition of front disc brake pads, if they are in need of replacement a preset little metal arm starts rubbing the discs and will make a whining noise. It doesn't do any damage but it's irritating to listen to.

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub

could be the CV axle or the hub bearing

It could be chopped tires or a front wheel bearing. Rub your hand around the front and rear tires and see if they are un-even like a wash board. If they are they need replacing and will make a wierd whining noise that changes with the speed.The wheel bearings can also make this noise so check the tires and go from there. I hope this helps you.....Dan
