Thank you for the info on the rear diff. It looks like the front diff also has a drain plug just below the fill, is that correct.
Yes that is correct, but the front differential is an oddball weight from mopar, every bit of research that I did people just switch to 75w90. Also is that the bottle does not fit to fill, you can either use a gear oil pump or what I did was put a section of hose on a gear oil cap and basically fill from the wheel well.
