It apears that drive flanges would be stronger than locking hubs, but what are some of the disadvantages. And how do the WARN ones compare with the poly etc. I'm running a lockright in the front diff, but even with the hubs locked if the truck is in two wheel drive, it should have no effect on steering. I plan to upgrade to 35 slpine axles in the near future and I'm trying to plan it out. Hubs or flanges. The truck rarely spends time on the road, other than getting to the trail.
