Rear transmission leak - Can't find part number

Post by Tman312 » Tue Sep 26, 2017 12:47 pm

Hey guys

My mom's 84 Tercel has a bad trans leak out of the driveshaft yoke seal.

I've gotten the seal that's for the output shaft and it is too small in outer diameter

Wondering if anyone else has replaced this seal and can shed some light

Thanks
Troy

I do not know what a "drive shaft yoke seal" is, do you mean the rear out put shaft? the one that the rear drive shaft plugs into?

those should be available, it is a standard seal, you have to order the correct part however. there is a thread o this forum with the seal part numbers listed. there are five seals: input shaft (rarely fails, you have to pull the trans to replace it), the two front cv axle seals on either side of the front diff, the selector lever shaft seal, and the rear output drive shaft seal on the end of the tail housing. When you order make sure you are ordering for the 4wd trans, all model years use the same seals.

Toyota PN for a M/T tailshaft seal is 90311-32010. Actual manufacturer is NOK- their PN is AH1904F. Sorry, no dimentions written on my seal.
if it aint there, there's a good chance it won't break!
83 SR5 Silver/Blue (Snowmobile/work beater)-totaled but drivable
85 SR5 Blue
88 SR5 White (the 'good' one)-not anymore-totaled

Love those Tercell 4x4 wagons but they sure suffer from road noise.
