Shaft slop help?

We also ran the shafts through our frame and used a bearing there to relieve some of the load on the outboard tranny bearing, reducing the cantilevered shaft distance. Hope that helps.

Thanks a lot! I didn't notice the the wheels , but you are correct.
Well, guess it's time to buy aluminum. Worst case, I think we have some long steel toughbox shafts we can cut down.
