5.13 Gears Installed ? regarding gear oil
I need some advise. I just had 5.13 gears installed in my Unlimited Jk. I was told that I should change out the gear oil after 500 miles. I want to put Mobil 1 Synthetic oil 75w-140. The question is the manual does not recommend this for the front differential only the rear if you are going to be towing. I want to put it into both. Does anyone see a problem with doing this. Second question is how much fluid should I be able to put back into both the front and rear differentials. I was only able to get just over 1 quart into the front and just shy of 2 quarts into the rear. Does this sound normal.
