Hi all. I have been looking on this site for answers to where I can find the fill & check plug on the front differential on my 2009 c300 4matic sport. Saw this asked on some threads and they showed a picture of it in the 3 o'clock position by the right output axle shaft. Mine has what looks like a frost plug in that location and is not where you could get at it because the sub frame is in the way. There is clearly a drain on the bottom. Do they use one of the bolts around the input drive shaft that is located by the bottom of the input shaft seal. I know there has to be one. I would be grateful for a little help.
Thanks.
