it actually is free. I have had mine changed 2X by the dealership. Just point out that the manual says it only needs to be change every 60,000 and then ask why yours needs to be changed at 12,xxx then 24,xxx. I'm sure after 60,000 miles it won't be but until then let Honda pay for the changes.

I must've missed something, but 12k miles seems ridiculously early to change gear oil.
 
It's very thick, and lasts longer than engine oil. It's usually 75w90 or 80w90 in these rigs.
 
Each 30k is plenty, even 60k is OK if that's what Honda calls for.
 
Any how, I found the pics, this guy did a great job documenting all the fluid changes for a Miata, I'm sure the CR-V's rear diff is similar:

You can "inspect" the quality of the gear oil by removing only the top plug.
 
To really see if any metal shavings are in there, though, you'd have to drain it.
 
CR-V sales were through-the-roof in May. Best month ever, nearly 20k units!

I was wondering about CRV sales since the news had coverage on trucks and SUV sales going drastically down. So I thought, well, we are a crossover, and not really a truck so are CRV sales down? And what about toyota trucks? Dh just got one and believe me, the demand was not down at all. It's not a major gas guzzler, takes about as much fuel as the caravan we owned before.
 
I never sleep by they way thinking about such nonsense.

Well, are things are relative.
 
The CR-V uses more fuel than, say, a Civic, but a lot less than an Explorer.
 
The market has accepted the CR-V as a reasonable alternative to those true SUVs, hence the boom in compact crossovers. RAV4 was up, too. Forester was up 66% compared to last year, but it is a new model.

My clue was a grinding noise from the rear driver side occasional. I'm not sure why it happened around 12 and 24,xxx miles on my crv. Could be that the differential fluids are less viscus when it gets to -40 around here or because all the snow I've driven through here in Minnesota. Another thought is that my differential may not have been driven the suggested 5 miles and then flushed again 2 or 3 times. I believe that is what honda suggests for the rear differential flush.

Hey THANKS FOR THE INPUT. WONDER WHY HONDA DOES NOT JUST FIX THIS IF THERE IS A MAJOR PROBLEM. SEEMS LIKE IT WOULD NOT BE THAT BIG A DEAL, AND PR WISE MOVE.

The "differential fluid" in the CR-V is actually a dual pump fluid. It has very different rheology that gear oil. It is very thin and runny. It is designed the provide hydraulic pressure when there is a pressure differential between the engine driven pump and the wheel pump. If there is a difference in pressure, the fluid activates the clutch pack and engages the rear end. Most of the time it is just circulated through the system, freely.
 
A thicker fluid would probably result in lower fuel economy, and possible unpredictable rear end engagement.
