Vibration at 55 and over

I just replaced my vacuum acuater to a manual pull acuater on the front axle. i just got on the freeway and at 55 mph there is a vibration that i never had before. About 60 it goes away and about 70 a slight vibration comes back. Any thoughts

Thanks,

Check to see if the front axles are locked in, that would make it vibrate..

Put the Jeep on jack stands, and see if the front wheels turn when in gear

I engaged the front end, drove it on freeway, and again the same vibration. Disengaged, and again drove the freeway, still vibrating. Is it possible that i put the fork in wrong?

Just a thought, but you may have a bad u-joint in the outer knuckle. I had one on my XJ and it cause me some trouble, but it would squeak at low speeds too.
You can check them by using a screw driver and see if you can move them around on the caps. That may not be it, but it is easy enough to check
