Bearing or maybe the driveshaft is out of phase.
Have you R&R'd the driveshaft lately?

Could also be that you just lost a wheel weight.

Well could be alot of different things. I would do what th said and jack it up and see if anything has an unusual amount of play init . Or you can just take it up to about 140 and then you wont notice the shake at 75 at all . Lol J/k
