Vibration at 70mph

Hey fella's, I have recently purchased myself a 2005 wk 3.0crd with 74500 miles on the clock.
When I get up to 70 there is some kind of vibration that seems to be coming from the Engine/gearbox kinda area. If I take my foot off it slowly disappears as the speed drops to around 65..

Anyone got any ideas?
I'm thinking some kind of bearing in the transfer case maybe.

Re: Vibration at 70mph

i had the same thing, probably it will start appearing at lower speeds soon, and will be accompanied by some whining noise.

in my case it turned out to be the pinion bearing.
i decided to replace all rear differential bearings. total material cost was 250,-

all vibration and noise are gone now.
