Local dealers seem clueless on this. When I stopped in to ask for the 2 grease types specified in the repair manual they had nothing of the sort at the parts counter. When I spoke to a service supervisor he said that they just use the single type of grease that a supplier brings in to them. He didn't know what it was, and had no idea that there were different types.

I bought Mobil synthetic and did it all myself. No problems so far.
