please help! vibration when letting go accel pedal slightly
Hello all i have a vibration (buzzing like) coming from under the truck when im coasting around 60mph and it only occurs when i let go of the accel pedal slightly so its not accelerating or decelerating. Only when im at the mid point of accel n decel.
Im sure Its not the wheel because i balanced all 4 and tried with my other set. What could this be?
Any advise would be appreciated.
Thank you so much.
I have 06 g55 amg.

Update:
1)Changed all 4 tires with brand new set of wheels- still have vibration
2)I found out if i put the gear in neutral when i have vibration at 65mph, I still have same vibration.
3)there are no play on all 4 wheel bearings.
What could this be?? It seems like I only have the vibration when there are no load to the driveshaft or engine and as soon as there is load, the vibration dissapears.

One of two things (that I had repaired).
1. The bearing from the front differential that supports the shaft that runs through the donut-hole in the oil pan to the left front wheel (4matic), or;
2. The transmission output bearing for the front drive (which supports the front propeller shaft).
If you experience this have them check both carefully, and pray it's the earlier, NOT the latter. If the front drive output bearing goes it's a transmission as the bearing is NOT available from Mercedes-Benz, no one makes an aftermarket replacement, and Mercedes-Benz states that the bearing is NOT serviceable. So you'd have to replacement the transmission. If you do find yourself in the latter situation, thank the dealer and pay him his diagnostic fee and find a good independent Mercedes-Benz specialty shop to do the labor on swapping the transmission, and order a replacement from Silver Star Transmission in Edmond, OK. They rebuild EVERYTHING and include a torque converter and a new MB valve body, and their warranty is much better than a re-manufactured unit from Mercedes-Benz.
