Power Train Tools Manual Locking Hubs

[GMC4wheels71]

Does anyone have any info on these? I can't even figure out how to get them to "free" or "Lock".

My 62 4wd does the wheel hop thing even when in 2wd so I'm thinking I'll unlock the hubs and see if it's still a problem.

It's such a boat to turn with the wheel hop and my being scared I'll tear something up that I'm really afraid to drive it with this issue.


Here's a pic from an old (2006) thread that went nowhere:




I'm pretty sure they're not OEM and I'm thinking they're not tool-less either because there's little screws driven into the hubs on the outside rim through the plastic.

It turns out these are re-branded Selectro hubs. How about that?
Anyone use those? Are they crap or good? Should I plan to pull them off and swap them for Warns?

Never seen them before
Almost looks like you have to grab the whole hub and turn it lock/free??
Wonder if it's from a NAPCO conversion?

For replacement part reasons I would update to a set of Warn Prem.
Did you try and Google um?

I googled them but my google fu isn't all that great. I found out that they've been called Sears brand, and Dualamatic.

They were OEM from many vehicles for years.
They are used on Military vehicles.
They were sold by Husky up until they were bought out by MileMarker and then the quality fell off.
If you have a model before about 1973 then they're great and strong enough for rock climbing.
They're hard to turn to "free" when they get bound up. (heh, my problem now I guess!)
I just this second found out that you do turn the entire thing. It's to make it easy to use with gloves or to keep them from getting snow and mud inside a selector knob.

That's what I've got so far. If anyone else more info I'd love to hear it.

I think I'm going to replace them with Warns when I get finished plugging leaks.


Do you think they're the cause of the wheel hopping in 2wd?

Yes, you just grab the knob and turn the whole hub to lock or unlock!

Thanks for the confirmation B&B. Do you have to take the screws out of the rim or they just turn?

You just grasp the whole knob and turn it, they are good hubs. Ive had several sets under the Selectro name and never had any problems from them. On the Dodge external drive hubs they are the only lockout available.
