2000 C280 with 98m. From inside the car I am starting to hear a bearing rumble. From under the hood, it seems to be coming from the water pump. With the belt off, it is indeed coming from the water pump and there is a bit of play when you rock the water pump pulley.

The procedure seems pretty straight forward, a lot easier than with the M104 engine.

Any feedback with the Graf or Laso replacement pumps or is this a situation where OEM is best?
