I was pulling a car out of the snow when something snapped somewhere in the tranny.
I was using the low range because the other car was quite stuck.
It just made a bang and wouldnt hardly move after that.
I was able to link aside with just small throttle.
Though backwards it "engages" a little better.

The sound (sympton) is like as if you havent completely stopped, and was a little bit fast with the parking postition on the shifter.
Like a tugging noise almost like it is waiting to rev down to be able to put a sprint in a hole....
And if it gets a couple of seconds it like "engages"...?
But you don't want to touch the throttle almost at all because then it pops out again with a bang!
In a flat surface I'm able to move but not more.

No axles are turning if you look under the car (at a standstill...).

What do you think this could be?
Is it the transfer box (the 4-wheel-drive box)?
Or is it something with the low range coupling?

And is it possible to change this by yourself (I've been doing cars for many years).
Or do you need a lot of special tools?

It was the transfer box (4WD)
Does anyone know what more models that use the same as the ML 55?
There are a lot of more of those other ML's than the AMG.

All ML's use the same transfer case. You can get one from EBay and install it yourself if you have a floor jack and tools.

Ok, thanks!
I got my hands on a used one.
And now it's installed and ready.
