What stubs / hubs do I need

[sope]

Another thread on here got me thinking. I didn't want to clutter it up so I'd like some opinions here. First I'll give you my D60 set up. I have a 1 non and 1 neck down inner, Detroit, 30 splite stubs, spicer U joints and Warn hubs. I hun 38" Bias ply swampers, a 305 and no doubler. My driving style and trails I run used to break 10 bolt shafts all the time running 35's.

My warn hubs have hair line cracks inside that make me nervous so I want new hubs (no flanges). This sounds like a good time to upgrade to 35 sline stubs. Now, what to get? My plan was to get spicer stubs and warn premium hubs. After reading another thread about breaking 35 spline spicers and upgrading to US Alloy. This got me thinking, with my set up will I break the Spicers? or will I even break the 30 splines and should I just get new 30 spline hubs. Another thing I was looking at are Dynatrack hubs. I am considering them. Who has broken Spicer 35 splines and what were you running? I've broken enough axles in my time of running 10 bolts and I'd like to avoid that experience from now on.

Any advice or opinions would be appreciated.

With a 10-bolt front and 35's, I broke 2 front shaft u-joints but never a shaft. With a D60 front and 38's I broke 2 and twisted 1 Spicer 30-spline stub.

If you are getting new hubs anyway, there is no reason in my opinion to not upgrade to 35-spline.

I have seen one 35-spline Spicer stub break under a 7k big-block rig on 42's, years of abuse, AND the little inner spindle bearing was trashed and grooved out the stub a little. Basically it was just about a worse case scenario.

The biggest problem I have seen on rigs with 35-spline Spicer stuff is not breaking them, but rather wearing out the yokes (egging where the u-joint goes) which lets the u-joint caps spin and get sloppy. I've seen this happen on both the above mentioned rig (tack welded the caps on) and on another fullsize big-block rig on 42's.
