Do front and center Diff fluids need changed as much as rear diff

I am a year into ownership of 2013 g37xS, 7AT. Just hitting the 40K mile mark, asked the Dealer about rear diff service and they said "all three" should be serviced at $109+per diff. Is it necessary to replace the center and front diffs as often as rear? I searched the forums some and didn't find a lot of info on this topic. I am exploring DIY on these diffs as well. I had a Subaru forester and did most of the maintenance, but it is much easier to slide under one of those! :O Thanks!

Its not difficult to change the fluids in these cars. If you're replacing the fluid in the rear diff, might as well do the front one and the transfer case, as well. Note the transfer case uses ATF, while the diffs require gear lube.

Thanks, I do remember reading some thread about the debate on what fluid to use in center, between ATF and 75-90 gear lube. I'm not a small guy so unsure about sliding my body under the car. I guess time to invest in some jack stands....

Been wondering this as well having owned the for 2 months and thinking about what I should do before winter.

Car has 69k (2011) and I don't have evidence any of this has been done. Owner's manual is vague and I don't see where Infiniti recommends replacing front/rear gear oil or differential and states transmission never needs serviced under normal conditions.

Plan on doing it eventually but unsure if it's needed now.

I'd do it...Got my car with 30k some odd miles and no record of it being done. Completed this a few weeks ago and the diff fluid was awful. Huge deposits on the drain bolt and stunk like something died.

Transfer case is also a must but that wasn't as bad as the diffs. All in all, it takes all of 1 hr and it was my first time doing that, ever.. Not bad to ensure your car's health.

I'd recommend biting the bullet and investing in 2 sets of ramps. Advanced auto has a 20% off sale right now and I got one set for half price. $80 delivered to my door.
