- 2002 Ford Explorer XLT
Hi everyone. My 2002 Explorer XLT 4X4 developed a hum in the rear. Just seemed to have started one day. I did not notice it getting louder. Don't think it's the wheel bearings. I have already been though bad rear wheel bearings. They hummed a lot louder and would get louder or quieter going around a left or right corner depending on which side was bad. The rear diff was rebuilt at the same time when the wheel bearings got replaced. This is a steady hum that starts at 25mph every time. Does not matter if I am on or off the throttle hums the same. Never replaced the half shafts and have 226K on it. Everything I read about half shafts say they clunk and bang. So I'm leaning toward the rear diff even though it was rebuilt.
Any thoughts?
