I was helping a buddy put radius arms under his cherokee yesterday. While we were getting teh c-wedges in place to tack weld them he was playing around and flexing it. It flexed good with the wedges being able to rotate around the housing and so I explained to him how this was the same idea as the bearing in the axle tube. Then I tried to get him to try an idea I had after I put my arms on, but he wouldn't try it. Enough rambling. Has any one tried welding the wedges to a tube clamped around the housing so it could rotate. My thought was to take a tube and split it. Then weld it up so it could be bolted together around the housing. Put a couple zerk fittings in it for grease. Weld the wedges to it. And then weld stops around the axle tube on both sides of the wedges so they couldn't move side to side. It would probably be better if the tube aroung the axle was machined. I haven't searched to see if anyone has tried this. I just figured I would check and see. This would put the point the radius arm rotates about at the center of the tube versus to the outside of it where wristing puts it. Just a thought. It wouldn't be that hard to do compared to wristing if you have to weld on wedges anyway.
