Auto locking hubs

Recommended Posts

Tried searching and haven’t found much info on rebuilding or repairing these. The FSM is terrible on this subject with just vague pics and not a lot of info. Since I won’t being using this truck for any off- roading I’m inclined to just roll with the auto hubs. Any good threads out there on this subject ? 

Heres some pics of what I have. The FSM shows an extra C clip that I didn’t have . The FSM doesn’t describe the “washers” well either. 

The only C clip I have was to hold the CV in place .

I've never yet heard of anyone doing anything with their auto locking hubs on their 720, only removing them and replacing with the manual ones.

Chooses are slim on the manual lockers. I was going to try and find some manual lockers in a JY, but I don’t think I can get all the parts to make them work( I.e , clutch part)

I noticed the Toyota’s run a 26 spline shaft. Anyone compare hubs ?

That looked kind of funny to me. My 82 manual hub stubs have the snapring on the end of the shaft. Looking at my manual that goes to 88 all show the snapring at the end of the shaft. Not the best design because I have had those splines on the end wear out and the snap ring has nothing to grip.

Nope- no extra snap ring at the end for this truck. It’s a transition year 5/83, so I got a little of everything .

Anyone tell me if the manual locking hubs (OEM), are self contained units? Anyone have pics of their manual lockers and how they break down on the end of the CV. 

SURELY someone has knowledge about the locking hubs

Replacing them with aftermarket hubs? Did they replace CV axles also? 

Anyone want to tell me what the outer snap ring does ?

I am not sure whether it is a year thing or auto vs manual hubs but my manuals show the end of shaft snaprings all years. It goes on the end of the shaft and retains the drive clutch for the manual hubs and you can set axle play by using different thickness snaprings. This is per my 1981 fsm  I don't think the autos were available until later. The other manuals were Haynes going up to 1996 but are known for inaccurate info.

The only thing I have ever seen about the automatic hubs is them being replaced with the manual ones. Never seen auto hubs going the other way.
