I would replace front & rear diff @ 24K cheap insurance and transfer @ 30K, when I bought my Jeep all three were low on fluid, just like my last 3 Chrysler products. Changed rear end fluid in my 300 SRT couldn't believe how dirty looking the oil was with 24K on the oil. Be sure to get friction modifier for rear diff. Wish there was a easy way to check transmission level, took my 300 to dealer to have trans check got it home still low, I had bought one of those Dorman dip sticks that you have to calculate level based on trans temperature.
I would say not more than 2 qts for rear, add additive 1st for rear diff, not sure about front would say not more than 2 qts but have ever changed it yet. I have 5 gallon pal with pump so I can't really say. We use a lot of it between 2 pickups, semi truck and all the other vehicle my son & I have to service. I've always reused plug with the metal gasket with no leaks or drips. Don't know how much ATF+4 for transfer case, not more than 4 qts????
I looked only shows motor oil, gas tank, anti freeze capacities, nothing for transmission, transfer case, front or rear diff except what type of product to use. I always write down in back of manual what I put in. But like I said earlier I use pump pal for diff until it runs out. I do remember that 8 speed trans take about 9 quarts + or - from what I read, what a pain to change fluid in these transmission but I'll probably try since I've seen some outrageous cost & labor to have this done $800 plus
Am I really way overfilled? I never thought I would ask a “what’s the capacity question” but I have never had an issue like this. When filling diffs/trans cases I realize it’s a loosey goosey within 10% or so thing on refill quantities sometimes but that is usually because you can’t get all of...
Yea the above article from Jeep Garage is very confusing with all the variances, but seems it should be filled to drain hole. How else would you know if it was low???? .9 quart for front diff, 1.4 quart for rear diff from chart in Jeep Garage, I will check this when I change my fluids with quart containers, still going to fill to bottom of fill hole.
