    have your tires balanced and make sure your lugs are all snugged down, one may have been missed when the bearings were done. When you have your tires balanced ask the mech if he noticed anything like one tire didn't balance right. A bent rim, mud on the rim or a broken raidel belt in the tire can cause it.
    Good luck

    take one thing at a time....start from the outside in.
    check the lugs. then go for the tire balance. next the tires and rim. then check your rotor, axle (but usually these will cause vibrations at all speeds).

    my Camaro had a similar problem a while back and I checked everything in the front end and it was all good, it turned out to be a U-joint. I never thought that a bad u-joint could cause a front end vibration but after I got both of them replaced the vibration went away. Just my two lincolns..

    Ha ha, my sister's Jeep has the same problem, it was in a wreck a few months ago, and still isn't fixed. I think the insurance co of the person that hit her is going to buy it. When you hit like 65, it starts to rattle really bad. They have had tons of people look at it, including 2 dealerships. They have also put on 4 new Good Year Tires and had them balanced 2 times. Either it isn't the same problem or they don't know anything, I will print this post out for my dad.

    Check your rear driveshaft. It may be loose where the yoke is. It will probably feel tight. If so put the transfer case and transmision in nuetral and then give it a shake. If it wiggles you need your driveline rebuilt.
