The diff would whine
at a pitch that would get higher as you accelerate, and quiet down when you coast.

i know what a centerberring feels like when it goes out and its not that because when i apply power in seccond theres no vibration... its only from like 0-15mph
how do i check tranny mounts and engine mounts? if i repplace should i get uuc ones? but i have a auto tranny so i don't think they will help

my firends car had the center berring and trans mounts go out and i kno how that feels. it goes completely away at 10 to 15 mph its like that initial accalaration. i think its heat related because in the morning when i go to school. i leave my street and am yet to feel it or hear it then but after that during the day it happens. that leads me to bieleve possibly no fluid in the diff but i don't know

They are oil filled. So you can see oil 'moisture outside.
If they are defective, the engine and the trans are 'hanging' in a different angle. This can cause also the drive sgaft to be out of the right angle and then you could get such noise.
How to change, see Gale's page. Link on my website.
Defective engine mounts also cause vibration in idle.

Check for oil outside, and cracks. Sometimes they are worne so that metal touches metal.
I changed both engine and trans mounts last year. Engine idle much smoother and trans shifting is smoother (at least I have that feeling).

maybe one of your brake calipers is frozen... does it happen when you hit the brakes too?

no i just changed the fronts and took the rear pads off and inspected them... so not the brakes
