A loud whining noise comes on around 40MPH and seams to go away around 65MPH. What is this annoying noise?

i don't know. on my older pickup, mechanic said wait
for fuel to be low and run half a tank of premium gas.
noise went away and i went back to regular fuel.

Check your power steering fluid.

The whining sound that you here could be coming from a number of places. It may be a coincidence but I think you may be talking about the transmission's pump. You may want to buy a stethoscope. This tool, if properly and carefully used, will help pin point a mechanical noise. Other possibilities are the power steering pump, tensioner and idler bearing, A/C compressor or A/C clutch, or Alternator. I hope this helps, write back if you have any other questions, good luck.

Change the transaxle fluid & add a bottle of Red Lubgard

Also do the Power Steering Fluid & add Lubegard to that

Still there-- I would guess the trans is failing

Too high a speed for a wheel hub bearing,but possible

It very well could be the strut.
smaller chance could be the CV axle.
Also have the splash guards/heat shields checked to make sure they are all tight in place.

The engine will have to be removed and inspected, to find out what has happened. Big expense, may need replacement engine.

Because the whine is still happening at high speed when your in neutral and low rpms it should not be engine or tranny related. I would start looking at wheel related issues. Hubs probably.

It could be that your shocks need to be looked at. I'm not sure what the specific repair would be though.

Whining noise is probably in one of the pulleys or belts. Probably the power steering. And the popping is probably CV axles.

Electric cooling fan bearing failed and the cooling fan needs to be replaced. Start with inspecting the cooling fan behind the radiator and determine if that is where the noise is coming from. Replace any worn or damaged parts.
Thank you for using fixya and be safe.
