fusion Posted February 28 Share Posted February 28 Hello, I have a 76 280z. I am putting a momo 3503 hub adapter onto my steering shaft. Every video I've watched of people putting hub adapters on their s30 it seems they slide right on. Mine goes on very snug, but I can get it to go on about 6mm or so before it gets really hard. Maybe I could pound it on, but doesn't seem right and I don't know how I'd ever get it off. I have checked the splines on both the hub and shaft and they look OK. I even bought another hub and tried that with no success. I have 2 other steering shafts laying around and it's always the same thing. Is it possible both the hubs are bad? Bought both from Amazon (not 3rd party either, from Amazon directly). The splines on the Momo look cast (not machined) and perhaps that's the problem? Not sure where to go from here. I like the collapsible design of the Momo but may have to consider another brand. Thanks for any advice. Quote Link to comment Share on other sites More sharing options...
jhm Posted February 29 Share Posted February 29 No, that definitely doesn’t seem right. I’ve used several aftermarket hubs (including Momo) on my various Zs; and never had a problem like that. Are there any other S30s in your area that you could try those hubs on? Quote Link to comment Share on other sites More sharing options...
calZ Posted February 29 Share Posted February 29 Is there some type of coating on the hub splines? From your second picture, it looks like something is either peeling or being machined off as you slide it on. I would try cleaning out the hub splines with a wire brush. It surprises me sometimes how little it takes to really jam up things with a tight fit. Quote Link to comment Share on other sites More sharing options...
fusion Posted February 29 Author Share Posted February 29 Cal, what you see in the splines is grease and I used it both for lubrication and also to show how far down the shaft the hub traveled. Quote Link to comment Share on other sites More sharing options...

I'll check into other s30s in my area but given the fact that I tried fitting the hub onto 3 different shafts already I'm really thinking that something is wrong with the hub itself.

Sorry…I missed that bit in your original post. Quote Link to comment Share on other sites More sharing options...
