Vibration when accelerating at low or high speed

[pumkin8481]

Hi
I have this vibration that I can slightly feel through my steering wheel but mostly comes from the rear of my 2009 ML when I accelerate from low speeds (20/30 mph) but also at higher speeds (70 mph) . She has done 103,000 miles so I'm sure there must be some mechanical wear but not sure.
I took it to my garage to be checked but they are not able to detect where the vibration is coming from. Has anyone else experienced this problem?

rear subframe bushes?

i had something similar once a balance weight came off one of the wheels although shouldn't be noticible at low speeds.

Propshaft bearings/mountings?

I would check wheel balance first...

Prop shaft 'donuts' worn or split /

Do the revs increase disproportionally to the speed increase?

Mat be a slipping clutch. Try manually selecting a lower gear and try again. If the problem goes away in a lower gear, you have identified the problem.
That being said, I'd also look at Drive CVJs and bushes for signs of breaking-up..
