E320CDI Vibrations Under moderate acceleration.

Hey my fellow DIY's. I have come upon a vibration issue with my 06 e320cdi which has 185k on it. The vibration feels like it comes from the rear under moderate acceleration and it changes with speed/rpm of vehicle. There no vibrations when vehicle is parked only happens when moving.

Things I have done to try fix it.

New tires, balanced.
New rear brake rotors.
Diff fluid second time around since I've owned it.
Suspension (struts) done all around at about 120k.

Possible solutions that I have thought of.

May need drive shaft re-balanced?
Can the axles go bad in the rear? or is that a rare occurrence? New axles?
Diff mounting bushings going bad?

That is all I can think of. If you have or know anyone that can help in chandler AZ are I would greatly appreciate it. Thank you. All suggestion greatly appreciated.

I should have mentioned that I have done those at 150k when they completely tore off.

Check out your center driveshaft bushing and bearing. If that has failed it would cause noise/vibration.

I agree with Motor or Trans mounts...but at that mileage I would replace the drive shaft flex discs as well. That was the cause of mine.

Thanks for the help guys, so just left the mechanic found out the flex discs and center bearing are fine. But my ENGINE mounts are bad again, last time i purchased LEMFORDER mounts 60k on them and they are out. Will be getting them replaced soon! makes sense why I started to feel weird shifting from my trans. ;(

UPDATE!

I would like to let you guys know that it was the engine mounts and trans mount causing the issues. I replaced all and everything is PERFECT! they lasted me about 60k!. Purchased OEM parts from AUTOHAUS AZ, they have great warranty and my old mounts were still under it, so I was able to get replacements at no cost.

NOW AS FAR AS REPLACING THEM GOES!

I went to a few local shops around PHX area and the lowest quote I got was $690 out the door. Let me just say that they were VERY EASY TO REPLACE! It took me 2 hours and I have never done the job before. If anyone needs help with their I6 CDI I will gladly help you out!

AUTOHAUSAZ has great warranty on them, and so does FCP EURO.

Thanks for all the help!

Update #2

DO NOT BUY FEBI MOUNTS! I did and I had issues with them, vibrations noise etc. I changed them out right away for LEMS! So far so good, will update in a few weeks/months. If anyone is getting ready to do the job make sure to have a flex 16mm combination/ box wrench, helps a bunch! Can also be done with flex ratchet 3/8" however it is more difficult.
