smile.gif Just a brainstorm near-topic..... Has Anybody looked into manufacturing stub axles?

 

The supply of stock pieces seems to be shrinking,

reasons:

- They wear, and break (see ZPARTS site) eek2.gif

- 240 racers want larger 280 axles

- CVJ conversions want 240 and 280ZX axles for the companion flange spline count.

 

New parts could be designed with a hub flange large enough for th 4.75" 5-bolt circle.

 

Is there enough material on the end of a stock Chevrolet axle :confused: that could be cut off, turned down, re-splined and heat-treated.

 

Wonder if Currie or Moser will take small prototype runs?

Ford/Mazda/Toyota/Nissan/Acura is easy as it's 5x4.5" (5 holes on a 4.5" bolt circle) which is the same bolt circle as all Datsun/Nissan (ie. 4.5" bolt circle, but we have 4lug/hole OEM). 300ZX Z31 hubs bolt on so that's the 'easy' front 5x4.5" install (brakes done separate) and rears can be redrilled JUST BARELY on the existing flanges where one of the original bolt hole locations is retained. I don't have a web pic handy of my redrilled units to reference, perhaps a customer does? Only ~1/32 of metal is left on the outer flange edge, I have it built up with a welded 'eyelet' for extra comfort. No room to drill a larger bolt pattern (ie. Chevy 5x4.75) on those stubs without more extensive mods.

 

For a Chevy pattern it may be simplest to just use a set of 5lug pattern change bolt on wheel adaptors. Nothing very unique involved so easy to service anything if ever required.

 

For Trevor's 'production' q's above, it's mainly the 280Z stub axles that are in demand and I haven't heard of many at all being broken. The 240 and 280ZX units are NOT in demand AFAIK. If you choose to use 280ZXT comp. flanges etc then you may experience binding as others have. That's the exact reason Scotty made his unique pieces and then him and I talked and they got tweaked a touch more and have now gone out for numerous installs. Customers typically use the 280Z flanges and stub axles which don't seem that short in supply. They're not overly available locally to me but then we don't have a strong used Z car supply for that generation locally anymore. US customers haven't had issues coming up with their own, I have some for those that do need them but prefer core exchange on the redrilled 5lug etc when possible.
