About how often are you guys changing your rear differential fluid on the G2 AWD?

I got the MM B16 code to change oil & filter, rotate tires, and rear diff. I have 13,350 miles.

I do tow a light jet ski trailer sometimes.

I never had an AWD independent rear end truck before so is this something you need to do every 15,000 or so for the life of the truck?

Thanks

Re: Rear Differential question

If it's like the last gen of the Pilot, the first change comes up pretty quick like yours. And when you see the fluid you'll understand why. Yuck!

After that it's about 25 to 30K miles and stays clean between changes.

The fluid is easy to change, Bernardi sells the stuff cheap and delivers it quickly.

The first time you break loose the drain plug can be a character builder.
It doesn't have to be that tight.

Re: Rear Differential question

Just changed mine for the first time. This is a pretty easy job - easier than changing the oil in my opinion.

Re: Rear Differential question

Be sure to use dual pump fluid 2, not the other stuff which I won't mention so no confusion. Dealers charge $80-$100 to do this. You can do it yourself for less than $20.

Re: Rear Differential question

Does anyone have the official instructions of how to change? I have seen Pilot videos where they drive the car in the driveway before topping off or at least start the engine.

2. Remove the drain plug (C) and the sealing washer (D),
then drain the rear differential fluid.

3. Remove the metal particles from the magnetic surface of
the drain plug.

4. Install the drain plug with a new sealing washer. Torque 35 lbs ft.

5. Refill the rear differential with rear differential fluid to the
proper level (E).

Fluid Capacity:
1.82 L (1.92 US qt) at fluid change
2.33 L (2.46 US qt) at overhaul
Recommended fluid: Honda DPSFII

6. Loosely install the filler plug with the used sealing washer.

7. Do the rear differential fluid air bleeding.
Start the engine.
Shift the transmission to P position/mode.
Wait for 1 minute.

8. Turn the engine off.

Re: Rear Differential question

#6....How loosely is loosely?
Just finger tight. You will remove it again to verify fluid level after the air bleed step.

Re: Rear Differential question

I like how it says to shift it to park after starting your vehicle, shouldn't it be in park in the first place?
I'm guessing they either mean from park to drive to park. To be safe I would do park, reverse, drive , low and back through that sequence. Now at what point does it remain for a minute ?

Good info and diagram. Is this a Honda-branded service manual or other?
Once the '17 RL service manual comes out (I presume this year some time), what do these manuals typically cost? Or is it a subscription service with no printed version?

PS how come the first of these fluid changes isn't covered by warranty?

This is from Honda's Service Express website, which is a paid access site. A member of the Pilots forums downloaded the pages and is sharing on Google drive.
Lots of the information is comparable to the RL. They both come off the same production line and share common parts.

Here is the link to the site. If I remember right about 250 megs of data available for the 2016 Pilot.
