Hi guys, I am wondering what kind of gear oil to run in my front and rear
differentials? I bought the XJ off a guy about three months ago and want to change the differintial oil just so I know its fresh. Does anyone have any suggestions on what brand and weight. I am running a LP dana 30 front with 4:56's and 8.25 rear with 4:56's. Thanks.

Capacities may vary. Correct fill is to the bottom of the fill plug hole.

In my opinion! synthetics are over priced and not worth the money. I dont see them as a bad thing just more money for what gain? I would rather change my fluids more often to get the dirt/particles out then run a "super fluid" and keep the stuff in there longer, i dont fully grasp that some oils/fluids can last 2-5 times longer then others. there is always the outside factor of dirt/moisture entering the fluid and adding to breakdown. however if it makes you feel better then great. It is your vehicle and should be kept to the best YOU want it. hope all this info is helpfull. You also can switch from synthetic to crude or vise versa, but its always better to pick and stick with it.
Merry X'mas!
