just wanted to say thanks for the great write up...you've given me the courage to try this, so I've ordered a set of lubelocker gaskets. They should be delivered in about a week, which works out good, since that's when I'll get back from vacation.

Does anyone know how much Gear Oil the Dana 30 and Dana 35 hold. I am planning to do mine this weekend but it is my only vehicle so once I start if I find I do not have enough I cant just hop in and run to the store and get more.
Thanks for the post! I bought my first Jeep yesterday and just finished swapping fluids. Did an oil change, front/rear diffs and t-case. I honestly dont think the t-case or the diffs has ever had the fluids changed. The T-case fluid should have been red and it was a nasty thick brown color and same with both the front/rear diffs. Now they have fresh oil and are happy! I just need to go back out and check for leaks here in a moment as i just got home from my test drive. Everything seems good.
Now i'm going to do a coolant flush and transmission flush tomorrow.
How can I tell if my axles have LSD or ARB lockers?
"Select-able" lockers like ARBs/Ox Lockers/E-Lockers will be activated externally. You will see air lines/cables/wires going into the differential housing & there will be controls in the cab. These require no special fluids or additives.
"Automatic" lockers like Aussie Lockers/Lock Right/Detroit Truetrac will have no externally visible parts, but will be easily noticed while driving on pavement due to locking/unlocking/ratcheting while turning. These require no special additives or fluids.
"Open" differentials are factory equipment on models with no traction control options. These can be identified by jacking up the Jeep & spinning one rear tire (while the non-running Jeep is in gear or Park) and seeing the opposite tire spin in the opposite direction. These require no special additives or fluids.
"LSD" Limited Slip Differentials can be identified by jacking up the Jeep & spinning one rear tire (while the non-running Jeep is in Neutral) and seeing the opposite rear tire spin the SAME direction. These REQUIRE synthetic fluid, or a separate friction modifier additive.
