1976 FJ40 Locking Hub (Fine Spline) Identification & Replacement Suggestions. (1 Viewer)

[Ackcruisers]

My drivers side locking hub continues to move itself to the locking position when driving. These locking hubs look like they’re ‘Aisin’, however the Aisin branding is not on them anywhere.

Can anyone recommend an upgraded new replacement?

This tack weld doesn't look normal..
Not sure why that was done.

That definitely would not be normal! It’s grease not a spot weld.

Ah ha!

Ah ha!

Any suggestions on what locking hubs I need to replace what’s there now?

These would be a OEM hub.

Warn would be the best aftermarket choice.

I replace some old Warn Auto Hubs on a 79 axle with new Warn Hubs. I had a hard time locating the OEM long body hubs. If you have a 76 axle you probably need the long body OEM hubs. Used 76 - 79 if I remember correctly.

Thanks @Shark56. My truck is from Colombia so it had stock front drum brakes and what appears to be a fine spline short axel from later FJ40s.

So I have the exact same hubs on a 77 I recently bought. They look like Aisin, but the name is not embossed in center of hub. Mine do the exact same thing, that is they won't stay in the locked position. Guessing these are not the Long Body style hubs for the 76 - 79 cruisers, and therefore wont stay in "Free" position.

Anybody got any ideas what brand hubs these are? Aisin counterfeits maybe?

Not sure what those are, but here are pics of the ASCO long body hubs.

Aisin counterfeits maybe?

"Counterfeit" is a little harsh, "Knock-off" may be more fair.

If you have the longer axle’s you need long body hubs. City Racer has a decent set.

Idk if they're aftermarket or not. They're fairly easy to work on. You can search here for threads or instructions . The dials should have small balls in the dials that work as detents and a spring.

I found pic from another thread from @RWBeringer4x4

I noticed your locking hubs used bolts to secure them to the hub. Factory used studs with cone washers, lock washers and nuts. Did your locking hubs have cone washers? Were they made for cone washers?

They look like these China clones.
