good luck marc, Hope it went well. I noticed they say change the brake fluid but not the rear differential oil.
Interesting. I would think they have DOT 4 brake fluid in the new QX's. I guess they think it will draw dampness.
I would have guessed that Infiniti, would have wanted the rear differential fluid changed quicker the first time, and longer intervals thereafter. You know, with the rear differential getting broke in and little metal shavings in the manufacturing process suspended in the oil.
I changed the rear differential fluid my Dodge Ram and at 19k miles it looked like chocolate milk and it was suppose to have been synthetic oil.
Granted it is a 2500 truck and I tow some, but the oil in the differential is very important.
It should be easy to change the rear differential oil. Fill and drain plug are facing rearwards and plenty of room to get to them.
Its such a well built vehicle.

Good strong frame and a big aluminum driveshaft. Make sure they check the air in your spare, Marc.
Have a good one
