strange vibrations

Here we go...88XLT with 5.0L Auto. I seem to be getting a strange vibration once I hit 60-65mph on th e highway. I'm not sure what could be causing it. Any ideas? It's been running great since I fixed the idle problem and installed a new muffler and tailpipe. I just did fail the emissions test here, but that is another story. I'm going to do an oil change, new plugs, air filter and clean out the throttle body. Could this help cure the vibration problem? I would appreciate any ideas! Thanks a bunch!

Look for a shiny spot where it looks like something was once attached, but came off. But I would be much more inclined to tell you to get your tires balance first; also I have found with these trucks that unless you use a quality tire with a not very aggressive tread, you will have some highway vibration.

Does the vibration seem to come from the front (steering wheel and pedals) or the back (in the seat)? If it comes from the front, it's most likely tires and/or worn suspension or bearings. If it comes from the back, it could be the back tires or the drivetrain.

Thanks alot, I just spoke with my tire guy and he seems to think that the tires are out of balance also. He also said that one of the tires may have blown a belt. The vibrations are coming from the front. Yeah this is very new...never had any sort of problems like this since I've had this Bronco. Thanks again.
