We hear a loud hissing/whistling noise from the front of the vehicle. We have been told that Ford is working on fixing the problem and would like to know if this is true. Thank you in advance for your assistance. Steve and gaylene schmitz

When vehicle is in motion, a loud squealing noise emits from the front hubs. Ford has replaced the seals twice and says there is nothing else they can do. The Ford dealership says the receive several complaints a day on this problem. Each time I see a 98 Explorer coming down the street, I listen and it seems all of them have the same problem.
