Rear Output Shaft still leaking after New seal install

So Tuesday night was a night of accomplishment. Or so I thought...

The GF and I replaced the rear output shaft seal, the one the driveshaft translates in and out on. At first it looked like it worked just fine... But after a few days I realized that I'm still getting the little bead of tranny fluid on the lip of the extension housing Bell or whatever we call it that the drive shaft slides into..

Any suggestions?

 

It's typically one of three things (in order from most likely to least likely). Either:
A) You damaged the new seal upon installation
B) The bushing in the tailshaft housing on the transmission is worn
C) The slipyoke on the driveshaft is worn/grooved where the seal rides

Typically though, in cases like this it's due to a worn tailshaft housing bushing in the trans, or operator error when installing the new seal. I've only ever seen 2-3 slipyokes worn/grooved in my 25 years doing this.

 

You don't happen to have a photo of this pushing do you? I'm not quite sure where that's located.

I guess the cheaper thing to do for now would be to replace the seal again and just assumed that maybe I damaged it. It did gets ever-so-slightly dinged up from the PVC I used to drive it in, but it definitely was not alarming.

 

It's inside the tailshaft housing. You'll need to unbolt the tailshaft housing from your transmission to really see it.

Basically, if your driveshaft slipyoke has a decent amount of lateral play in it, the bushing is probably worn. The driveshaft is supposed to slip in/out (fore/aft) in the transmission, not up/down.

 

I like to use wooden dowel to get seals installed instead of your PCV method, works well and have not had any comebacks from leaking seals yet.

 

So if I roll under and try to shake the drive shaft with my hand, is this something I should be able to feel?

I don't have a photo to you? I'm just trying to visualize what it would look like. Did you kind of like go around in a circle wwith the Dowel and the hammer?

 

Yeah lightly tap it in with a small dowel, usually I have some extra 6 inch long 1/4 inch dowels, Tap on one side then the other side and work your way around it evenly, I like this method since I can still see the seal and it doesnt matter what size the seal, I would assume you would have to get a different sized PCV pipe to install different seals.

 

I guess I might try to replace it again and try to be more careful this time. I also need to make sure the fluid level is okay

 

Can the bushing be replaced without removing the transmission or the housing ?

 

Have you guys figured out anything after replacing the seal I replaced the seal and it is still leaking I looked at a bell-housing extension for the transmission and its 450 dollars I'm not trying to spend that is there something in the extension housing that can be replaced instead of buying a whole new one?

 

When you installed the seal, did you pack the area around the steel spring with red grease or something thick enough to keep it from popping off the rubber seal?

 

I took out the original seal with a seal puller then I put in the new seal with the 1/2 PVC I didn't use any grease or anything because it came pre-lubed with grease inside the seal. The only thing I can think I did wrong was I put it in there too much. I remember it wasn't flushed it was in there more than usual. I bought another OEM seal so I will be trying it again this week. Fingers cross it goes away.
