Manual Locking Hubs for FJ40

[knuckle47]

Is the same 79 45 you emailed my shop about working on? If so, we have the correct Aisin locking hubs in stock.

Thanks Matt, yes… but I do prefer the Warn hubs. They are easier for me to twist from lock to unlock compared to the Aisin hubs on my other truck…. You available for a call today after 1pm eastern? Had the wrong area code

Yes sir.. we can get the Warn’s too. They are about double the price and half the strength though.

Absolutely, Aisin Steel body hub vice - ??? No issue with the Warn… I’ve used them on multiple vehicles. But, if You ever take an Aisin/ Asco apart and compare them to another locking hub…Well. Proofs in the pudding.

I have thought about a type of modified bung wrench to use for the Aisin Hubs as an assist…if they are truly that much tougher, that may be a plan to follow. As I did say, over the years 3 other FJ40’s that I had all used Warn hubs without issue. Sucks gettin‘ old…really

I was happy to get the Aisin upgrade when i put the 83fj60 front disc on my 74fj40.
I thought i could have used either at the time.
Cleaned, painted and rebuilt the Aisin (yes, i had to chase that spring-loaded bearing all over) and they twist smooth and satisfyingly "click" into place.
If i recall, the key was to lightly grease, not pack them too Full which makes them hard to turn. Fwiw.
If my warns were close, I'd have offered them up but they are a few hours away.

I launched that small bearing into orbit…Pretty sure it passed Voyager II into deep space.

I could definitely make a Aisin hub wrench.

Does anyone here know which birfields will work when doing a disc brake conversion (FJ60 parts) and updating the locking hubs to the FJ60 hubs?

Thank you

Swap the 60 birfs onto your inner axles. Grind the inside of the axle ball to fit the larger birfs.

Here are the photos @Jdc1 sent me as he was doing mine… the difference being the spline count on the new birfs. The old ones are 6 spline like the last photo here
