Ever heard of the output/coupler/input failing completely on a 10 spline 465-205? Heard they wear out and get sloppy, but complete failure?

Well we wouldn't care that they wore out if it didn't mean failure. That's why 32 spline is better. 10-spline wears and fails. But all of mine are in good shape.

Yeah, if the coupler doesn't stay well-lubricated, it dries out, rusts out, wears out and either spins the splines out or just shatters.
Is there a beefy 10 spline coupler available in the aftermarket? Thanks, Kevin

Oh I have personally destroyed one to the extent that the biggest piece was the size of a nickel!!!

If they make it any beefier, it won't fit inside the adapter. Just make sure it stays lubricated and you should be fine.
Personally, I never had a problem with mine.

Just use the 32 spline version. That is the upgrade.

So once one goes does it take the tranny output shaft and t-case input shaft with it??

Not from what I've seen.
I have the SM465/Rockwell T221 that was originally in my truck, and the sleeve was worn down almost smooth inside. I have a SM465/205 combo, and the splines are worn about 1/2 way through, and the edges are SHARP. I have a 2nd 465/205 combo that appears brand new, the guy who gave it to me said it came out of a brush fire truck that had less than 10,000 miles when it caught on fire and was totaled.
On all 3 of these setups, the transfer case input gear still looks brand new. Only the sleeve and the output shaft of the 465 are fubared.
I wanted to upgrade to the 32 spline, but GOOD LUCK finding one. Only used in 1985-1991 K30/V30(3500).
So...I am now going with a divorced t-case.
