I have a Honda PIlot 2011 which I took to my local Shell service shop . The code the car showed was B1236. One of the many things they did was to change the differential fluid. After I picked up the car from the shop, I noticed a slight sound from the rear wheels when I would make a right turn. I took it back to the shop and had them look at it. We did a few sharp right and left turns and we heard nothing. I drove the car away and a few days later noticed the sound to be more noticeable. At this time, I took it to my Honda Dealer. They noticed that the fluid in the rear differential did not seem to be right one and the sound was because of that . Can a wrong fluid damage the rear differential?
They are also recommending that we change the rear differential which off course is extremely pricy.
I would really appreciate some views on this…
