This van has been trouble free except for periodic brake jobs but has now developed a growling/singing sound from the front end. It is a growl at low speeds and a singing sound at higher and highway speeds. Not related to which gear its in, it goes from low growl = low road speed to high pitched sing = highway speeds. I suspect a differential problem, does that sound right? I plan to replace the vehicle soon, but was hoping to leave it to spring. If I do nothing but live with the sound, is it likely to make it through winter (say four more months)? What is the worst that could happen?

Good afternoon,

It sounds more like a hub bearing on the outer part of the axle by the wheel. That is a very common issue for this type of noise.

Can you tell what side it is coming from?
