Gear oil - mobil 1 synthetic - $9/qt = $45
Use whatever satisfies the specs I sent you; transfer and diffs are different if I remember correctly. Use whatever brand meets the specs, don’t sweat the brand.......unless you want to ?Is the lube the same for the differentials and the transfer case? I went to Pep Boys last night and all they stocked was Peak Gear Oil. I could try Auto Zone or another store if there is a strong preference for which oil to use. Thanks.
You are so very welcome, great to ‘pay back’ into the MUD community again !!I had the most wonderful experience today visiting with cme4lyt, who graciously volunteered to change the oil in the differentials and transfer case. Besides the fastidious manner in which he did the work, he was a wealth of informaiton about the FJ80 and some of the places I could explore now that I'm in the Bay area. And his rig; amazing. V-8, rooftop tent, dual batteries, refrigerator and the coolest conversion of the tailgate to a useful storage space. What a nice way to spend a Sunday morning, and what a kind and generous person to meet. Thanks so much, Jonathan, and everyone else who guided me in this process!
