I have a 93 Explorer and am experiencing a noticable front end vibration at highway speed. I have replaced the front bearings and shocks a year ago, have had the wheels and tires "dynamically balanced" (on Hunter equipment, off vehicle) and have replaced the radius arm bushings, also a year ago. I have also replaced the front end sway bar bushings. What else could be the source of this problem?
Thanks, John

Thanks for the replies, guys.
When I had the tires balanced, they were also rotated. It's possible that there is some tire action goin on, because, the two front ones, now on the rear, had some cupping from a misalignment early last year. I would have thought that they would have worn out this cupping by this time, 15K miles later.
Hallsound: How do you check the ball joints?
Thanks

I am getting this problem also... However it started happening since I had my upgrade from 16" S wheels to 17" AU2 on my XR6.

When I get to 100 or so I get this humming noise as if there is something going wrong aerodynamically.
