Having trouble figuring out the problem on my GL... Maybe one of you guys had something similar.
My GL550 is making a clunking noise when accelerating from a stop sign or a traffic light. Especially heard when not coming to a complete stop (slow down to 5mph and accelerate).
Took it to a good reputable shop today, they have checked over all the mounts and possible weak spots that could cause the noise, but everything is tight. Engine/trans mounts have already been replaced recently.
Noise is coming from underneath somewhere in the middle of the car.
Mechanic told me that it's most likely something internal in transmission or the transfer case.
Said that most likely the chain inside the transfer case got loose.
Considering just taking it to my local MB dealership and have them look at it.
