I'm curious about the differential fluid change which I just had done by the dealer for just over $600 (Cdn), about $440 US. How much fluid did it take? The TSB on the bad differentials suggested 2 quarts. The dealer charged me for 3 bottles at $111.65 (Cdn) each which is about $81 per bottle. I know the markup on this oil is outrageous, but I was interested in determining whether I was ripped off by the quantity they claimed to use.

Curious as I also have a '21 3.5.
Did you see any discoloration and/or metal shavings?
Have you noticed any smoother shifting &/or driveline quietness?

I did not see any metal shavings on the drainplug (pictures attached). I asked for and was given a small jar of the drained fluid which was essentially black and very thick, like licorice yoghurt (if it came in that flavor) in appearance. I haven't had it analyzed. I really haven't noticed any change in the vehicle but did it as a matter of caution.

This is what I used. 3 liter bottles was perfect for both the front and rear differentials. You’ll need a 24mm socket with a breaker bar, a 10 mm Allen key and about 30 min to do both. On the front removed the tire and a little access panel for ease.

I have to say after all new fluids I’ve noticed when in sport mode 1st to 2nd and 2nd to 3rd gear changes don’t seem to lag as much.

So a total of 3 liters did both diffs? And they charged me for 3 liters for just the rear. Scam.

Here she is all cleaned up. I bought her in February 2021. Done all her maintenance myself.

Yup
