light clicking noise during take off and or stopping when car is warm

I had the same exact problem on my 2000 ml55. I spent hundreds of dollars at the dealer w/out any success. Then one day I noticed that the shifter in the councel was slightly moving to one side when I would take off. It rurned out I had a broken motor mount. Once that was replaced all the noise went away.

Problems like this may best be resolved by someone with a lot of experience with this vehicle. That may be from a high quality Mercedes Independent, or the Dealership. They see many problems on these vehicles, and they may have seen this before.

Front wheel drive ? if so could be constant velocity joint not a repair for a backyard mechanic

There are 2 torsion adjustment plates on each side between front and rear doors on undercarriage . Pull bolts out and grease with marine lube ( or something just as durable) . Remember to mark bolts when removing as they control height of vehicle. I had this same prob on my ml55 , they sell a bushings kit for this but it's not worth buying as problem will re-occur everyonce in a while. This home remedy is extremely effective.
