I've seen this on Chevys mostly. Remove driveshaft, clean off the yoke and fill er with some gasket maker, and let it sit overnight.

In the rust belt of Ontario we call that self undercoating.

ive seen this plenty of times. The hole in the yoke is to allow air to vent while the driveshaft moves. Its pointless tho bc that air can stay right in the trans with no harm done. Theres a diverter in the transmissions to prevent fluid from going that way, but it usually isnt re-installed when transmissions are rebuilt, or gets damaged or stops working. I just fixed this problem two weeks ago on a ‘85 chevy S-10 drag truck with a 2 speed powerglide. Most people fix this by covering the hole with silicon but it doesnt last that long so the proper fix is to weld the hole shut.

The vent on top is plugged. Fill the hole in the yoke with rtv.
@craighatfield63912 ай бұрын
If that plug doesnt come out the seal will leak. Opening the top vent will stop it.

if its anything like a 7004r / 4l60 there is a cup shaped device pressed onto the output shaft that has an internal o ring that mates with the driveshaft yoke stopping fluid from running down the splines and out the vent hole. Its probably damage. i have just sealed the hole up in the past with silicone with good results

Thanks for the tip but this one doesn’t have that. It’s just a pressed in cup at the end of the yoke that keeps fluid in.

That plug is above the fill level of the transfer case if im not mistaken. If the transmission is leaking into the transfer case, it will overflow, and come out of that plug. I bet if you take out the fill plug, a quart will come out on the ground, or on the floor where that pile of ATF and floor dry is.

So trans leaking into transfer case. Change the transmission seal....

i see that alot on chevy trucks, not on others usually. the weld around that plug cracks. normally just replace the u joint and yoke. but i've JB Welded a few to save the customer money.

I was suprised the price of the yoke. It’s only like 350. So yoke and joint it is.

Yeah, i've seen it quite a bit too, but then again, I did work in a heavy duty shop that had a drive line shop inside of it. So I saw all sorts of weird stuff. Especially when it was big, companies and the driveline was twisted... We'd ask the driver what happened... Ended up being the mechanic that pulled it out for us. I say let me guess. Just barely let off the clutch at a stop sign with a laugh and a chuckle.... Mechanic would go fuck no damn filipino drivers

I had same thing on my 2010 Dodge Ram 2500 at first I thought that transfer case output shaft seal was leaking and I bought the seal but before removing the drive line and did further inspection and found that it was yoke was leaking, I sended that plug with sand paper and cleaned with brake cleaner and apprlied high temp silicone all over that cap and it fixed the issue , after that I put 60k miles and still no leaks.

That’s your fucking mistake for not checking that when you had it apart
@screamindieselltd2 ай бұрын
Didn’t have the driveshaft apart son. Visually the pressed in plug looks fine. Didn’t leave till about a month later when it started seeping.

You don't know what you're talking about. More likely to go 250,000 than anything built in the last 10 years.
