Rear differential oil change.



Using a 3/8” ratchet remove top plug on differential cover. (remove top first to be sure you can get it out to facilitate refilling after you drain it)





Remove lower plug and drain. The lower plug has a magnet on it to grab loose metal particles that may accumulate in the differential oil.

Lower plug with “stuff” on it.





Stuff





Plugs. Use a thread sealer to ensure no leaks after you install the plugs. I used Permatex Thread sealant with TEFLON.





Torque plugs to 25 ft-lbs.





Fill with 75w-140 Synthetic oil ONLY





You are done. Total time for me 15 minutes.

Welcome to the Spot! Did you drain it cold? that stuff is thick if it is cold.

Yeah it was cold but the front I did right before and it came out like normal.. Pluss I used like just a hair under 2 quarts and it was running out of the fill hole.. I have a pro comp 6 in lift if that makes any Dif.



Thanks for the welcome

I know it is kinda pricey, but you might wanna do it again. LIKE NOW.... Slow, even when cold it should take the required 2.5pints. With your lift your pinion angle might be wrong, causing it to overflow quicker than desired. I would be worried about the "sludge-like" fluid having a LOT of shavings in it due to worn or wearing parts.

2.5 quarts? the fluid that came out was clean and clear. I will see if there is any thing blocking the drain whole. It was not sludge lit it was just draining as if through a small whole

Then a blockage is likely the cause. Maybe some teflon from the factory or similar. Goodness forbid they actually do some QA when prepping these things for shipment.





Quarts - Pints.... Tomato, Tamoto.... LOL

Is it really 2.5 quarts and do I need to jack up the rear an force some more in there?

I suggest a call to Greg at PRG. I don't have a lift and am not sure if the one you have is messing with your geometry or not.

The lift changes the angle of the diff so you will get less in there before it starts to spill out. If you had the mag-hytech diff cover you could get over 4 qts in there. <img src='http://www.titanspot.com/Titan/public/style_emoticons/<#EMO_DIR#>/002.gif' class='bbc_emoticon' alt=':smt009' />

You could park facing down hill and top it off. Dont drown your axle though. You should do the axle vent mod too.

Hmmm, didnt mean it to be smart azz. Simply tryin to help. Really, if you park you truck down hill you can get more oil in there. Easier than jackin it up imo....
