    Anyone one this forum change their own FWD and Rear Differential Oil. If so can you let me know which weight oil and pump you used. Any helpfull hints, want to get done by next Saturday. Did you change out the original washers. How about lock tight. I like to do my own maintenance but have not done this before, so what ever you got please let me know.

    Thanks

    For the love of god, do not use locktite on those fill/drain plugs.

    New washers are always recommended. Does everyone replace them every time? No. Does everyone who doesn’t replace them have leaks? No. Are you more likely to get a leak reusing a washer? Yes.

    I use 85W-140 in the rear and 80W-90 or 75W-90 in the front. What type of a climate do you live in?

    Manual calls for 75w85. Good luck finding THAT anywhere but a dealership for $35+ a quart.

    Went with 75w90. Synthetic. No pump needed for me due to the 6” lift. I used a $3 bottle/hose adapter.

    For the love of god, do NOT use lock tite!!!

    I generally don't. I have had good luck reusing mine.

    I use Valvoline non-synthetics, they are cheap and easy to find. In the differentials, use hypoid gear oil, it will be marked on the container.

    As mentioned above, get an oil pump. You can buy one at any auto parts store, they are about $11 if I remember correctly. The pump is just a small PVC, hand actuated pump that screws into the top of the gear oil containers. You can do without the pump in a pinch, but you will have to get a piece of flexible hose and put it on top of the spout on the oil containers and squeeze the oil into the differentials.

    Another consideration, and this is pretty important... ALWAYS remove the fill plug BEFORE you remove the drain plug. It would be quite a mess to drain the oil only to realize you can't put new oil back in.

    Fill to the plug level, or slightly below. Don't overfill, if your differential breathers ever become clogged you will develop leaks.

    Did mine in May. Piece of cake.
    Did A LOT of research. Use these fluids. Shop around for the best price:

    Did mine (rear & front) three months ago.

    Be on level ground.

    Get a $10 hand transfer pump. Got mine at Lowes.

    Redline 75W90 full synthetic.

    Reused the washers.

    For the love of the devil don't use thread locker.

    75W85 is what Toyota calls for but finding it can be tough. Although Redline, which is excellent oil, is becoming more readily available. 75W90 works just fine for most of us. I run Valvoline SynPower 75W90 in mine. I also replace the washers every time. A washer kit is $11, just replace them. Follow the specs that @Haggis777 posted, he's spot on. DO NOT use lock-tite. DO crack open your fill plugs before removing your drain plugs. You don't want to find out you cant get a fill plug out after you've drained your diff.

    Thank you, but I stole with pride.
    One of our Tundra brethren posted it a week or two ago and I just happen to have it handy.
    He DID layout a nice chart for this task!!!

    True story, although there is some debating if Ravenol is the same as the Toyota branded fluid or if they have more additives in the factory fluid as it is more expensive than gold.

    I'm currently in Pewaukee, WI, but I just have them ship directly to you. It usually arrives in 2-3 days.

    No no no. DO NOT USE LOCKTITE. That would be a very bad idea.

    I changed my transfer case oil yesterday. Everything I saw and read said I should be removing a 24 mm bolt, which crush washer. But this is what I had instead. Wondering if anyone else had this.84656ECB-BA25-43E8-BBD7-06E92E0B311E.jpg A plug with pipe dope on it, can’t torque it so I marked it applied Teflon tape and reused. Might go by some 24 mm bolts for it on the next change. But I would say no previous leaks or current leaks. Used 3/8 ratchet extension to remove and replace

    Yep, that’s your X-fer case plug.
    They’re like that in the later years. Personally, there’s no way I would change it, if it was supposed to be a bolt it would have been. It works so I’m not messing with it.
    Just MHO, I didn’t stay at Holiday Inn Express, YMMV

    Case drain plugs have tapered pipe threads, which are self-sealing as they are tightened. I have never seen teflon paste or tape used on any drain plugs from the factory.

    If you have a problem drain plug that always leaks, then I don't suppose teflon paste will hurt anything, but thread sealant on case drains is typically unnecessary. I would worry that the addition of sealant could affect the delicate balance between over-tightening and leaking. Better to install the drain bolt like they did at the factory with trace remnant of lube, new washer, and torque to spec.

    On threaded pipe connections, pipe dope or tape is used more to reduce the friction in the threads to achieve maximum engagement/maximum sealing rather than acting as a sealant. That's why pipe dope/tape is made out of Teflon. Maximum engagement is not desired in the case of drain bolts. I've read numerous threads of owners rounding out the recess in that plug you're holding after someone has over-tightened.

    Sorry to contribute this after the fact...just saw the thread. Maybe it will help the next owner changing his diff lubes. :(
