Hey guys, i need some help.

Ive noticed some gear oil all under the bottom of my truck and tonight i pulled the drive shaft to make sure it was leaking from there. Apparently it is leaking from behind the nut that holds the flange on?

I went to the steelership last week and bought the seal. (well the guy behind the counter was like, "uhhhhh i think this is it...."

I was hoping maybe someone could verify the part number.

SEAL, TYPE T OIL
90311-41007


I was talking with Jay351 and he told me it is simple as taking off the nut, pulling off the flange, pulling out the seal and putting the new one in, tighten down flange, stake nut, bolt up driveshaft done!

Just making sure if that is the best way to do it and making sure there is no special tools needed (i was told a seal puller is necessary, but idk)


Also what size is the flange nut, or whatever it is called?

Thanks a bunch.

I just rebuilt my T case and trans, I wrote down the seal #s that came out and the seals sourced from Marlin that went back in. That # does not look like any I wrote down. The rear output seal should have one arrow on it if it is a Toyota seal.The front output has two arrows. Also, use a new nut, torque it to 90 ft lbs, and use a sealer on the splines of the output yoke. Read the # on the seal itself.

 

I can't even find any seals on marlin.

 

Well maybe i should refrase, maybe its not called the output shaft seal

Its the flange where the rear driveshaft bolts to. Fluid is leaking from that seal

 

That is the output shaft seal. Where did you get the seal #? Off the pkg or off the seal?

 

That is off the package, it is unopened and looking through the packageing, i cannot see a part number on it.

 

The # is molded into the seal. Do you see an arrow? I have only got a gasket set from Marlin or Toyota, so I don't know the individual #.

 

okay i just opened it, there is like a white greese on the inside, which i thought was like a plastic untill i opened it and got some on my hand. on the seal itself it says

koyo- MTO41A1

 

Yea I See A Little Tiny Arrow

edit: sorry for the caps lock

 

Nut is a 30mm

 

Thank you, i need to go buy a socket to take care of it

 

Bump, is this possibly the part number??

Thanks again

 

Go to this site and plug in that Toyota part #, it will list all the applications for that part #.

SEAL, TYPE T OIL

 

Hey Thanks a bunch! So im guessing from that whole list of parts that it is pretty universal between most yotas'. And judging by this one i guess it is.

Thanks MT. Goat!




Also, just to clairfy, all i do is take the nut out, slide the flange off replace the seal and put it back together. Is there any tricks or tips while replacing this seal?

Thanks!

 

Pretty much like doing the pinion flange seal as described below:
http://www.4crawler.com/4x4/CheapTri...eal/index.html

No seal puller needed for the t-case flange seal. One tip is to apply some RTV sealant to the splines of the output flange before putting it back on the output shaft to help seal up that area from leaks. Picked up that trick from Marlin.

 

Thats what jay351 was telling me. GOod advice, thank you!

 

I have a slight groove where the seal rides. It doesn't feel like much with my finger but when I slide the new seal over the groove it does catch.

Anyone have any experience with speedi-sleeves?

 

In case that flange nut gives you any problems, here is my prefered method for removal...

 

thanks for the tip. Mine had already been staked three times and the 3x wasn't pretty. I hacked it up with a sharp chisel and bought a new nut.

 

what do you mean by stake the nut??
