Check the threads for "differential" should find some helpful info. I changed at about 3700. Nice and dirty with slimy residue and ionized "goo" stuck to the magnet (not sure if it was metalic). Needed a 10mm hex wrech and used Semi Synthetic Durablend. Uses just under 2 quarts. No thread sealer needed. No special pumps needed either.Targa Florio said:I noticed in the owner's manual to change the rear diff oil after 3 mos/3000 miles if we tow. Anyone have experience? Tools required? What kind of oil?
Done deal, not much to it. Squeeze till it comes out the fill whole. Just under 2 quarts. Can use different viscosities dependent on you local climate, check the manual (warmer climate, heavier oil) :temphot:Targa Florio said:Thanks guys. Does diff oil always smell so bad? BTW Redline spec'd their 75W90 synthetic for us.
I just squeezed the oil bottles best I could and got most of it in the box. Is that the way you do it?
We don't have a true limited slip differential; there are no clutch plates that require a friction modifier. No adatives are necessary or desired. Use a quality synthetic 75W140.cinco-cero said:Does a friction modifier need to be added to the rear differantial?
Most limited slip rear-ends need this additive. My local nissan dealer offered to sell me a "kit" for do it yourselfer's. The tech I talked with was about as sharp as a sack of wet mice. He couldnt give me a concrete answer as to whether or not an additive was needed. He then said Nissan has an additive for limited slip rear ends, but it wasnt vehicle specific. The additive alone was $40.
75W-140? My '07 owners manual states 75w-90 synthetic for the rear and 80w-90 for the front.scr38 said:We don't have a true limited slip differential; there are no clutch plates that require a friction modifier. No adatives are necessary or desired. Use a quality synthetic 75W140.
Nissan changed the rear lube specs to synthetic 75W140 for the rear of the Titans. If you do much towing I would use that. I have Amsoil Severe Gear 75W140 in my Armada. If you don't tow the 75W90 will be fine. If you live in a warm climate as I do I think 75W140 in the rear is a good idea, towing or not.cinco-cero said:75W-140?

I'll be the third to ask. If we don't use our Armada's for towing we need to change the diff oil anyway???Gom said:so if we don't tow, when should we change the oil??? someone else had asked but he didnt get answered...
