Rear seal leak?

[kemo sabe]

It's a 91 1500 w/ r700. When I don't drive it for a while I'll get a spot of trans fluid under where the rear of the Trans meets the drive shaft. I'm thinking it's the rear seal. Any input would be great.

is your slip yoke pulled out in that picture? if so then i think theres more that needs to be replaced in your tranny than just the rear seal.

Nope that's just a rear seal without the dust boot

I've never replaced one. Do I just pop the old one out w/ a screwdriver and press the new one in gently with something like a nylon mallet?

i believe you need a certain tool to do it properly but i imagine a screwdriver would work and what not.

I ended up replacing the rear seal. It's still leaving a spot when it sits for a couple days. I can see little drops of Trans fluid forming on the end of the driveshaft where the u joint is.

i had similar issues when i swapped to a TH350 in my truck, the 4L60E yolk has a hole in it, for some un known reason, i swapped to a th350 with no hole, and i was good to go.

That's weird. Yea it usually takes around 5 days for a spot of fluid to show on the ground.
