For a little while now I've been having this strange drag/vibration in the rear. Some here have said that changing their rear diff fluid helps or solves the problem so I thought I would look into it.
When I bought the X in October I had my local shop do some work. I dug back in the paper work and found that the refilled the rear diff w/ synthetic 75w-90. According to the manual that is wrong so I decided to change it out.
According to the manual the rear axle requires synthetic 75w-140 with 4oz of XL-3 Friction Modifier. So I went to the dealer and bought what is needed.
Just now, I damn near have the drain plug out and I happen to notice "75w-90" embossed in the rear diff case.
So my question is, what oil does this thing take and what would you do?
Thanks!
