I cannot get the rear fluid dif fill/drain plug to budge.... Just seems to be slowly rounding and I don't want that.... Can I drain and fill through the speed sensor? I know that I will have to pump the fluid out and in. Please let me know!

 

I would certainly replace the plug. It's very little money relatively speaking, and a good shop will be able to remove it. They can use heat, etc to get them free.

You can do it yourself as well, but you may need to have the car on ramps, etc.

Do it right now while the car is still ambulatory.
