My wife's 2002 Explorer XLT, 4.0L, 4x4 has developed a humming noise from the rear of the truck, concurrent with wheel speed. Putting the tranny in neutral at speed does not make it go away, nor does putting it in 4HI. The tires look fine, and a cursory visual inspection of all 4 rear CV boots suggests that they are in good shape, as well.
The truck has 110,000 on it, and the tranny has recently been given a clean bill of health by a local, trusted tranny shop. I don't believe it's brake-related, but I'll inspect this weekend.
I remember a similar noise on a Saturn VUE we had several years ago. That turned out to be a bad wheel bearing. I wonder if this is the same situation?
Is there a common failure on these trucks with respect to wheel bearings? I've never done anything with the rear IRS on these trucks, so I don't really know where to start looking.
Thanks for you help,
Greg
