A quick question. Is the axle filler plug on top of the axle shaft on the passenger side? That is the only thing that looks like it could be a filler hole.
Thanks

Look at the diff cover, see a big plug there? That's it. The bottom cover bolt is the drain. The thing on the axle tube you see is the vent.

Maybe I'm blind, but I didn't see any big plug on top of the differential. Is it supposed to be visible from the front or rear?
:banghead:

from the rear, you should need to use an allen wrench to remove it

 

[jeff denton]

Look closely at the big cover on the rear of the differential. The plug is about 3/4" in diameter, has a hole in it where an allen wrench would go into it. Maybe yours is covered in grunge and yuck, you'll need to scrape around with a screwdriver to find it. It could be hiding in front of the panhard bar. But it has to be there somewhere!

At the right of this photo, you can see the filler hole on the differential cover. About halfway up the cover. Differential cover

As Jeff has said, it may simply be obscured with gunk and dirt, and there's the possibility the panhard bar is hiding it from your view as well.

Could be a lost relic.
Haven't y'all heard of the "Differential Shroud of Torino?"

It has an uncanny resemblance to the Patron Saint of C.I.H. --- RallyBob!

I can see the masses flocking to the hills of CT hoping for a glimpse.

Ok, after lighting a few candles to the patron saint of the CIH, low and behold, there is a big plug that takes a big allen wrench to undo.

Thanks guys.

Was some one / thing sucking up? :haha: :haha:

So, Dan, was it covered up with grime or what? Do we need to discuss some hygiene at the risk of causing this thread going totally spaghetti?:lmao:

 

[Dan-MI]

No, it wasn't all gunked up. I was looking too far up. I thought that the plug that was easy to see was too far down the cover to be a filler plug. It doesn't seem like you would get much fluid in using that one, but if that's how it's supposed to work, who am I to question the German engineers?

 

[Paul]

Dan,

The location of the plug in the cover is at the "Full" level. This way you add gear oil until the level comes up to the bottom of the hole, now its full. This makes it easy to check the level during routine inspections as well. Remove plug, if you can touch the oil level with the tip of your pinky finger, there's plenty in there. Same is true for the filler plug on the side of the 4-speed tranny.

As far as I know, all gearboxes are oiled like that unless there is a pressure pump system. The spinning of the gear throws oil around to lube everything. The diff housing has passages that send this oil to the pinion bearings even.
