I read so many post about breaking Birfields and other issues with axles and carnage. Are the Dana 44's stronger or more reliable stock compared to stock FJ40 axles? I have a 1978 with stock axles, what should I expect?

The 40 series axles are equivalent of a Dana 60, the 3/4 ton axle. If you are worried about breaking them, upgrade the Birfield and you can sleep easy at night.

I am running 33 x 12.5 mud tires. I have a 383 stroker sbc in it. I have a clicking in hte passenger side front end when I engage my front hubs. Never changed a Birfield before, that is why I am asking. Thanks!
HAHAHAHAHAHAHAHAHAHAHAHAH. HAHAHAHAHAHAHAHAHAHAHA.
Get back on your meds, bud.
The 40 axles are stronger than that of a stock D44, but not in the same ballpark as a D60.
Looks like I am going to have t o learn to change my birfield anyway as it is clicking. Sounds like I can hammer away with a set of Longfields and run 35's without much worry. We don't have much rock climbing here in Michigan anyway, mostly woods, mud, sand, etc. Thanks!
W/ the 35's you're right at the point where the stock knuckle stud strength *may pose a problem. If you keep it off the rocks, install the Longs, you outta be safe. Pack in a few extra studs & a spare knuckle....
For the later 12mm studs 80ft-lbs
ARPs take 120ft-lbs
(If I stop, s*** will start falling off!)

Do you have a pciture of the knuckle and studs you are talking about? Sorry for the dumb question but I want to be sure we are talking about the same thing. Thanks!
Actually......according to the ARB catalog....the stock LC axle is the same diameter as some of the D60 axles. 1.31", IIRC. Others are 1.50", but like I said....some;p
