okay, so we have an 87 22re 4runner with 235,XXX with a tranny leak.
its low on fluid, i know i have the w56 not sure of transfer case tho.
these questions may seem dumb so bear with me, being 17 i dont have the funds
to burn up a tranny and pay for a new one, and yes ive tried searching (if
you find anything i will gladly read it, i just wasnt able to find anything relevant).
i have a (stupid?) question but im gonna ask any way cause its
baffled me for a while, i understand the the transmisson and transfercase
both have seperate filler holes but do the share the same fluid an the two
fillers are to make sure fluid is distributed all around? im just curious if the
3.2 quarts of oil in the transmission joins up with the 1.7 quarts of oil in the
transfer case and make 4.9 quarts somewhere, or do they stay
seperate, i couldnt find it in the chilton or the factory orange yota manual.
i have a small leak from the transmission, but my bigger problem is a leak
from the rear of the transfer case, at least thats what i believe it is.
the leak is where the the transfercase (?right?) and Rear drive shaft meet.
is this my rear main seal leaking? (think thats right) well, i want to obviously
get some tranny fluid in there, and i figured id go synthetic but i want to fix
this leak so im not having money leak out allover and be in the same situation
on with lighter pockets

Btw you can be jealous of my skills in paint not really.....

so we've identified the location of the problem, its inside there... rear main?

this is the small leak up near the transmission fill hole, the plug next to it... what is it? and i was
wondering if i take that thing out clean it up and put some rtv on it will that stop the leak? eh?eh? eh?

overview of major leak. so this is my transfercase right?

so these must be all noob questions but id rather look like a fool now, then a fool with no money
cause he let it go an burned up his tranny. Please correct/school me on anything i have wrong
because im not a 100% sure on
what i believe i know, and tips are welcome and extremely appreciated!

From the front of the truck, it goes engine, transmission, transfer case. The transmission and transfer case have separate fluid, and it's your transfer case that it leaking. I would say it's the rear output seal on your transfer case that is shot http://www.oreillyauto.com/EW3/Displ...ycleCount=2060

you'll need to pull the driveshaft off the transfer case and get the output flange off to get at that seal.

the little bit next to the fill plug is the reverse light switch, if I remember correctly. you could probably pull it out and put a few wraps of teflon tape on the threads

Before you even contemplate doing any repairs, take it to a pressure washer and blast all the dirt and slime off - you do not want it getting in when you pull something off.

The 'leak' around the reverse light switch does not look like more than a seep. You can replace the washer and be done with it.

The seal at the transfer case output is not hard to do. The easiest way to remove the nut holding the companion flange on is to use a breaker bar and socket, with the handle against a frame rail. BLOCK THE TIRES. Have someone start the truck. In first gear (IIRC, verify the direction of rotation), with the driveshaft removed of course, have that someone gently let out the clutch until the companion flange begins to rotate out of the nut. Then stop the engine and proceed to remove the flange and replace the seal.

Use the old seal to drive in the new, or a block of wood. Be sure to grease the seal before inserting the companion flange, and use RTV on the splines of the output shaft to seal around it as well. Tighten the nut (best to use a new one, but not required) to 90 ft./lbs., and restake.

quick question, are the rear and front output seals interchangeable?
autozone has the front and not the rear, so i want to know if i can buy
the front and use it as the rear seal?

Pretty sure they are different. I had the same leak, on the front driveshaft output though.

Was very straight forward once I got everything apart. With the tranny in 1st and t-case in 4low (to keep everything in place)my 18" breaker bar removed the nut with ease.

Go to toyota for the seal, it probibly won't be much more then the cheaper seals you get at autozone..

I didn't have anything to put the new seal in, so I GENTLY tapped it in with a screwdriver. It was greased so it slid in without any problems. Tap it in using a start pattern to make sure it goes in straight.

Keep some rags to clean up with, it can get messy....

Old trick: use the old seal to drive in the new one. Then you can use a ballpeen hammer with fewer worries. GENTLY tap and do not misalign though. And don't forget to
1) clean the splines first, with brake cleaner, on the output shaft and companion flange. Take a look at the companion flange for grooving where the seal rides. You may need to visit the boneyard for one better than yours. You can lightly hone the sealing surface with emery cloth if needed.
2) RTV the ends of the splines/inside of the companion flange. Otherwise oil slowly seeps up the splines and slings all over creation.
3) grease the seal lips before sliding in the companion flange. If dry, the new seal can go south in a hurry.

HTH,
