Does anyone have obe of these...is there a way to verify its a 300m steel?

Is this the T-case output?

[trei75bronco]

Yes sir

Are they still made? I'd be pretty interested. All the references I could find were from around 2005.

I think the BC shafts were made to the same dimensions as the stock shafts. Unfortunately the stock shafts are one of the few parts that don't have a dana part number stamped on them. There could be some differences in the radiuses between the journals and splines though. The stockers are as square cut as can be.

Here's a stocker.

I looked at my spare one vs the 300m shaft and the machine work is night and day different. . Phil instead of a breather the guy installed a hose fitting and reason?

the probably added the hose fitting so they could locate the breather up higher

Thats what I was wondering or extra oil port?

Used to get the vent above the creek level. That straight fitting would be tough to fit without a body lift. Usually you need to find a small 90 degree fitting.

What's up with that bearing in the stock output shaft? Looks like more than 13 rollers and looks like some kind of center race.

First does that look like a aftermarket shaft..? Second I have a 1" body lift so hopefully it's enough. . I have the roller bearing packed in grease with a tube insert holding them in works good

[Viperwolf1]

Yes it does look aftermarket.
