Have your mechanic check the wheel bearings and the transfer case.


It's most likely your wheel bearings. They don't always get loose when the wear out. Most I've changed are still tight when you wiggle the wheel and don't make noise in the air but sound awful with wieght on them. I was able to tell they were bad when I had them out in my hand


Wheel bearings. I've been through 3 sets on my blazer. 170,000 mi.
