Squealing axle seal. My van has been doing the same thing for months. Use a can of spray lubricant with an extension wand to spray behind the inner cv joint housing. You're trying to get the lube onto the inner shaft of the joint which is hidden by the joint housing. At the dealership, I used Mopar Spray White Lube. It lasts the longest; up to two days, but the noise will come back. The only cure is a new seal. You can also spray Mopar Rust Penetrant in there but it doesn't last much more than a few minutes. At least that's enough to prove what the problem is. WD-40 might work too.
