Kert with these 1480 joints, You are gonna start snapping np205s

Not when he's running the same size joints downstream of 4-5 times gear reduction.

Probably won't have any more trouble breaking driveline u-joints though. Good job

Now maybe he'll be breaking traction instead of parts

I'm hoping I just don't break anything now.

I suppose it will be axle joints next.

So, these 1485's and 1410's that are coming stock, what angles can they operate at? The axle joints are pretty deep and I think that is where some of the angle comes from. Somebody told me 50*+ with some grinding!!

ill ask the main drivline engineer today when im at work

the max he recomended was 6 degrees contunious and he said you could push it to 13 degrees contunious, now we also use the same joint in the 14 bolt front in the DCX and its operates at up to 37 degrees but not constantly, So if your looking for the max end of the specs i would say make sure you use a quality joint that you can greese, the sealed joints are great but with large angles the greease breaks down and leakes out pretty quick and the the brinneling starts and the joint starts to run hotter then the rollers tend to fracture and the joint fails

Wow, that's pretty shallow angle on the one end!

yea it is, but you have to remember this is what they shoot for in stock GM trucks with a 100,000 mile warrenty so you can run higher angles you just get less life, one thought that i had though is to some point a little higher angle might prevent the false brinneling from setting in with a higher angle the cap actually rotates more around the Trunnion than at lower angles so you get more ratchiting motion which may help keep the lub more evenly dispersed.
For as long as ujoints have been around there is actually a lot of things that are unknown in there operation, for example you set a clearence in a engine bearing for oil film there is no such clearence in a ujoint becasue nobody really knows the film thickness of grease its pretty intresting stuff when you get into it.

Any progress? Just curious how this may have worked out.

Still playing with it. did the mating flange but wasn't happy with it so scrapped it and will rework.
