I was at the dealer this morning having my oil changed and they recommend changing the rear diff fluid as well. The SA said my fluid looks dark and had some air bubbles in it. I read a post here a few weeks ago where the guy stated "I wouldn't touch any of the differential fluids unless you drove through deep water"

Do I need this service?

Thanks for your help :D
