727 Leaking AGAIN??

[98 SNAKE EATER]

OK, so last weekend out of nowhere, the output shaft started leaking


It had been sitting for over a week while I was out of town and not a drop was found on my floor.


Then I pull into my shop and while putting her on the lift to check the brakes and whatnot, I noticed a small drip which turned into a puddle within the next 1/2 hour :confused:


Checked the U-Joints and one was bad, so I replaced them along with a new output shaft seal and all was good :cool:


Took her out for joy rides multiple times this week and again, not a drop was found on the floor


Then earlier today, I pulled her out from the back of the shop to the front so I could mess around with her this weekend.


Probably had her running for no more than 5 minutes and parked.


After sitting for an hour while I welded up some lift off hood extensions, I now see another puddle on the ground :confused:


I'm gunna replace the seal again to see what happens, but I have a funny feeling I may have other problems as she was actually ~3 quarts low when I got her just a couple weeks back :disgust:

Mine used to leak from the input shaft.. I had it redone and it stopped leaking but was soft shifting and no fun...then it started leaking again....I give up!!

Yank the tail shaft housin off and inspect the bushing. I bet it's toast. Check the drive shaft slip yoke good too.

I always put a light layer of grease on the yoke before installing it into the new seal also.

Rusty took the words right out of my keyboard. If the bushing is wallowed out bad or the yoke is worn the seal won't be able to accommodate the extra movement and you will have a leak.
