Differential or Transfer Case Service at 100k miles?
Afternoon, I have a 15 ML 350 2wd and I don't believe the transfer case or differentials have ever been serviced. Should I get everything done? Is transfer case required for a non 4-matic car and do I need to do both front and rear diffs or just the rear? I would appreciate any feedback. Also would this be a good price? Thank you guys.

I change mine (both front and rear differentials + the transfer case) every 100 000 km (around 60k-65k miles). It might be overkill, but it's very easy to do it yourself. Plus it's not very expensive.
Labor charge for rear differential is reasonable. Fluid shouldn't be more than 2 liters -- $29 seems about 2x what retail price is for Motul, but you will be buying it in a genuine MB plastic bottle (lol).
Does Mercedes have an official published differential and transfer case fluid change interval for the W166, or is it one of those "lifetime fill" deals?
