'flange' mounted u-joints on Tcase - educate me please

[will e]

I did some web searching.

I am looking at buying an Atlas transfer case. It has the flange mounts instead of what I normally think of as a yoke mount.

I take it you bolt something similar to this to it:



What are the advantage and disadvantages? One advantage I think I see is I could carry a spare one of the yokes, if I brake mine its a bolt off/bolt on fix.

Main advantages is it is more universal. You can put whatever size yoke you want on it. You can swap yokes faster. etc.

I have personally never seen (Or even heard of actually) a flange mount failing. As in the bolts actually sheer off. Since they are spread out farther, it requires more torque to break them than the shaft. I have seen rock bouncers blow the guts out of Atlas's (Which is why most have stopped running standard t-cases) but the outputs be fine.

My Cherokee had a flange mount on the back of the D20 from the factory. My JK uses flange mounts on both t-case outputs and both axles. J10 uses yokes on everything.

Having flanges are MUCH easier to deal with for a wheeler. Quicker replacement, and when you are grinding it on the rocks it's much more likely to stay intact.

It's only a couple minutes to swap out the driveline on the race car due to this.

I have normal yokes on my atlas.

I know that Toyota uses the flange style yokes on landcruisers and they aren't known to fail. Mine sure haven't. They are a little easier to change out as well.

I say go with the flange style.
