Love external hubs but for a wheelin truck, I'd be tempted to switch to an internal hub setup. With that said, there was a day (before Ebay) that I had litterally dozens of the blue actuators. Used them in everything. Of course they are all gone as are the all metal hubloks that were used on the 60-66 3/4 tons. Man I should have kept that crap.
I've thought about going internal, and have 4 sets in the shed. I cant get them to seal up and hold 85-140 in and keep water out, and I have set upon set of wheel bearings for the big hub setup aswell, all used but still usable.
2 years ago when the spicers came to me bezels were available at the GM stealership near my house, it would have been way too easy to buy them then....
It's fair to say I have hubs coming out of my #$&, and none as a working, usable pair. we'll see if superwinch will ship direct, or e-bay will e-mail me.
Edit: I have hub locs on the truck now, they seal up good but are so old and beat up that I have to use a crescent wrench to turn the dial. The center pins in those are always bending and the ramp design to engage the hub is not well thought out in my opinion, I started making center pins out of 8 penny nails for strength but they bend too, the only part in those hubs like new must be the springs......bought them for 20 bucks a few weeks ago, wondered what they came off. I went thru and put new o-rings in the dials and cleaned them up, one of the gears/teath on the hub itself had not been all the way locked in last time they were ran and it bent the tooth just enough that it wont lock in now. I'm far past filing these to make them work, when I get a shop i'll set up a wall o' hubs...kinda like a journey thru time thing...lol
btw, autozone,napa,kragen,motion,victory.....they have no availability for these hubs, all special order at best. Makes you want to look around and start guesing what wont be available next, could have a nice retirement fund if you were to guess right
Edit: looked again on superwinches site and they list the 400517 as discontinued....i'll call anyway and see if there's a set on a shelf in thier shed, maybe for cheap.
