It seems to be around 45+ when not accelerating, or with light acceleration, but it's not consistent, i.e. some times it's worse than others under the same conditions. Feels as if it's coming from the rear.
The vibration could be a tire. I have this on my '94 Camaro. Turns out that the two rear tires are making vibrations with every rotation. Could be ply overlap or some other construction cause. I had chased this vibration for over a year. I spent a lot of money 'fixing' things that didn't need fixing. I finally found the problem when I took the car to a shop that had a tire balancer with a road force measuring device. It puts a drum up against the tire to simulate the force of the car on the road while rotating it at speed. The tire was fine as far as balance was concerned. But still it would provide a shock impulse with every rotation. This machine also checked the rims to make sure they weren't bent, out of round, etc. This, of course, doesn't mean that there isn't something wrong mechanically. It is just another thing to keep in mind and is much cheaper than some of the things I did while chasing that damned vibration.
Some axial play, in/out movement, is normal. Is only the clips retaining the axle. Some radial play, side load of CV, is normal too. Trans have sleeve bearings...
Things to look at: Wheel balance Bad tire and/or rim Dying wheel bearings brake "upgrades"

Could be the hub bearings. Does the noise change when you make a right or left turn? Another poster said tires, might be a good idea when you have the car in the air to check the hub bearings to swap the tires front to rear and see if the vibration goes away or moves to the front.
Could be bearings, I have changed the right rear already, but I don't notice a difference when cornering, it doesn't feel the same as when the right side was going bad, and I don't feel any play in it. I might change it anyway, and have been considering swapping the tires around to see what happens.

Usually a shim or vibration at a certain speed and higher is a tire balance issue. Something to do with frequency and resonation of the suspension... Get the tires balanced somewhere first before you go crazy... A decent shop should balance all four for about 20 bucks. Ask which tire was the worst out of all four and ask for a printout if they can to prove the balance was done. I have seen tires roll into my old shop that were only off by .25 cause a complaint of a vibration, usually only at high speeds. See if there is a cleaner, or even dirtier spot on the rim where weights get attached to, maybe a weight fell off.
Also check for a bent rim. Aftermarket rims are made from CHEAP metal.
