Rear Hubs, How about welding for 5 lug conversion Options

[914gem]

Has anyone tried building up the metal like on the 70 hubs by welding? I hear so many people crying how thin the later hubs are. Any ideas on if this would work or not?

Why does everyone stress over the OUTER rear hubs. Once you do the conversion, you find what I'm talking about.

ANY early 911 outer hub using the same bearings will fit up into the bearings in the trailing arms. The "trick" is in the INNER stub axles. The splines for the outer hubs are different than the splines for the 4-cyl hubs. I'm surprised nobody came up with axles to use 914 CV joints on the inside (trans) and 911 CV joints for the hubs.

This is kind of what ended up with our race car when we went to a 915 gearbox. We went with new axles to mate up with the output flanges on the trans (911) and the new axles had stub axles built into the outer CV Joint. (perhaps this is how the late model cars are?) My point is, the 911 outer CV Joints appear to fit inside the trailing arms so why not just adapt the axles and use 911 parts? (they may have different splines, but it should be easy for a machine shop to do splines for new axles) I swear this would be MUCH cheaper than the thieves selling original 914-6 stubs and hubs and safer than trying to modify 4-cyl hubs.

For our future track car, we simply bought the outer 911 parts and had the 914-6 stubs from our old race car, but I may try to just do axles on that one just to find out....
