New lift and ?

[xrock]

Just installed the OME heavies on my 94 - Did the 4 coils (2 spacers up front) , 4 shocks, caster bushings and steering stabilizer.
(also rotated the tires while they were off)

Everything went pretty smoothly and it drove nice on the way home.

here's my question and I'm hoping someone else has had this and can point me in the right direction.

When you reach about 70 mph there is a slight vibration/ hum. To best describe it would be either:
1- the sound of a mud tire buzzing or
2- like you're traveling next to a ricer Honda with the goofy muffler sound. Not like your RIGHT next to it, but if it were a few cars ahead. Make sense?

If anyone has run into this, please let me know. I'm going to get under there in the morning to triple check that all bolts are secure and look for any unusual "wear" marks.

Thanks

Do you have any extra weight on the vehicle? If you don't, you probably have a well over a 2.5" lift, and you may be hearing your drive shaft u joints.
