Howling from passenger rear
So a couple weeks ago my wife was complaining about a howling noise coming from the passenger rear. She said it sounds like a motorcycle is beside her. I pulled the wheel off and gave it a once over. The rotors needed replacing. So put on new brakes and rotors. Also spun the hub to check the bearing. Bearing spun a little hard and was making a clicking noise. So I replaced the hub assembly. They noise is still present. I've also tire rotating tires. Anyone have any ideas. Diff maybe?? The howling does get a little louder while going around corners

Rear Evaporator Howling sound?
I have a 2010 Chrysler T&C with the 3.8L. We had no cooling two weeks ago and my mechanic found the rear evaporator coil on the passenger side leaking refrigerant pretty bad, so $650 it was replaced. I now have cooling but when driving locally from 5-45 mph I will occasionally get a howler monkey sound on the right rear of the van, at highway speeds it does not do it. The sound literally sounds like a howler monkey, no joke. It lasts for maybe 3 seconds and goes away, it is not consistent and does it whether the A/C is on, ***** are on heat or cooling, it may make no sound for awhile, then all of a sudden you hear it and its gone. At first it sounded like a motorcycle (crotch rocket) going by but we noticed no motorcycle near by. I have talked to my mechanic and this is a first for him. I am wondering if it may be one of the actuators in the passenger rear? It never caused this sound until the rear evaporator was replaced, could it possibly be a part in the rear evaporator unit itself? Any help would be appreciated.

Before tearing things back apart...Have them put a/c gauges back on and recheck high and low side pressures and for full fill of refrigerant,making sure that rear a/c is full on. It's a pretty long distance for the a/c compressor to pump from the motor to the rear and back.
