I was told it was Cat. Converter but had that removed, and still makes the loud roary vibrating sound from the back area. IIt does not do it all the time, and seems to do it worse the longer I drive it.
Its prob the diff or axle bearings. Also check brakes
Testimonial: "It was the muffler, thanks tho."

it's possible you might need to just change the trans case fluid.... it's a pretty simple task, i usually do all the small minor work first before i take it to a dealer to fix.... if they said you need a new trans case, but didn't tell you why, more than likely there might be something you could do yourself to make it better... those service men have been working around vehicles long enough, they should be able to tell you exactly what's wrong!
i would also do a tranny fluid change to... some of the noise could be coming from there too -- when you change either fluid, add a little lucas transmission fluid stabilizer, it helps alot with seals and makes the fluid stick to the gears better...

This sounds like a noisy wheel bearing, they really can get loud, but quite when u turn because the weight comes off the wheel..
SOURCE: Makes a low roaring noise when you are at crusing speed.
One of the front wheel bearings are bad. Jack it up and see if one is loose, the noise will usually change if you swerve back and forth while driving. Could also be a rear pinion bearing in the rear axle.

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub
