Hey mann777 - in your write up, you said "I used for the Front Mobil 1 and for the Rear Toyota OEM." Why did you decide to go with Mobil1 (75w) in the front and Toyota OEM (85w) in the rear? Assuming you have a reason for this, otherwise you would've just used the same for front/rear.

I went online to the Toyota TIS - Techinfo Toyota and downloaded the chassis maint. info--hope it's helpful.

I'm not advocating any particular Gear Oil as there may be other brands that have this same option. But I must add, it was really nice and convenient and clean to use the new Amsoil bags of gear oil. Check them out. LIke I said, there may be other companies doing the same thing,

Changed Differential Oil
Mann,
Just curious why you used 2 different oils for Front and Rear Differentials? Your helpful guide has them both as the same gear oil. Also, did you buy your plugs and crush gaskets from the dealership? Thanks for sharing, very helpful. I'm planning on doing mine soon. Chris M.

$2 to $3 each. Might want to replace the bolts too while you are at it. The front has the hex fittings so be careful not to strip them. Any Toyota dealership usually has the plugs and definitely the crush washers on hand. 12157-10010 are washers for rear fill and drain. Also fits front fill plug. front drain is 90430-24003 big ole copper washer. Transfer case uses 90430-18008 for both drain and fill. If you can change your engine oil, you can definitely do this job. Get the little quart bottle pump at an autozone and it's back where differential oil is.

Did this service today. Used the 6 crush washers above. Used about 5.5 qts of 75w-90. I wanted to share a tech that you folks with fluid transfer pump grief may find useful. It's the highly technological and sophisticated "tube"
Its 1/2" OD - 3/8" ID. it fits securely over the gear oil caps and allows you to invert the container to dispense every last drop without spills. Whole service took about 3 hrs and a couple beers. She needed it, for sure. Unknown if rear diff was ever changed. Front and transfer looked a little better. All were well.. "tanned."

2007 GX, 91K miles, fill and drain bolts look pristine on the rear and transfer case.
Going to change out the fluids this weekend I will not be be using ramps or jack stands . Wearing xl~xxl shirts these days. On a 4Runner change I found dropping the spare gave me ample room to fill the rear differential. From a search on this thread it seems this has not been addressed so no need to drop the spare? Transfer case looks like I will have good enough access.
Under the truck for the front I'm not able to look straight up without a near nose plant on the skid plate. I'm fairly sure I can remove the skid plate. It will essentially be a blind removal but kind of doubt getting it back on is doable. I can't tell once off whether I will have the room to do the job. Go for it or punt the front to the shop?
