manual hubs vs. auto..
I have a 94 f150 with manual hubs. I dont go off raod much but do use 4 wheel drive every month or so. I find it a real annoyance to get out and turn the hubs. Ive considered switching to auto.
I was just wondering how many people have actually had thier auto hubs fail on them. My last truck was 90 K5 blazer that had auto locking hubs and they never gave me any problems and the truck had 200,000 on it.
Ive heard rumors that auto hubs break.
So any feedback on thier reliability would be great.

My old 77 blazer had manual hubs that had been changed over from the auto hubs,a lot of owners didn't like the front turning all the time and said it inproved the gas mileage having manual hubs.Anytime I went out to the hills and the weather was bad I would lock the hubs in so I didn't have to get in the mud to do it.They have a come along way on the making them better to hold up,but like anything you buy it will break at some time.I read on the form here to kick it in 4 wheel around town on drive across town (no turns low,speed)to keep them working if you dodn't go out off roading much it helps too lube the front up and free up what kicks in too the have front turn when you need it.I've used mine a few times and it nice to turn a switch to get 4 wheel drive.But have 5 or 10 pickups and out of them there will be 1 or 2 that the 4 wheel drive will go out on it,being used wrong or not at all.Alot of people buy 4x4's and never go off road with them all the time they have the vel.After tradeing it in,the next owner it breaks on when they go out 4 wheelng.Well thats my 2 cents worth,Nice talking with you

Even the new Super Duty auto hub fails, and those are mucho expensive.
Go with manual locking and like the previous post said, lock them if you think you might need them. Then all you have to do is kick the t-case in 4x4 and your good to go.

Not to hijack your thread but what way is "LOCK" and "AUTO" on a 99 SuperDuty?? Mine are not marked. I think clockwise is "locked" but not positive. As for auto hubs go I would not waste money on them. As Colorado Osprey said they all fail at some point. You will get better fuel milage with manual hubs provided they are not locked in

ALL AUTO HUBS FAIL

My 91 f150 has a bad auto hub. I personally don't trust auto's especially when the front differential leaks and could be empty, and the thing is turning while going down the road without lube. When you get up to not even 20mph and the thing comes unlocked and grinds like crazy and makes the wheel extremely hot. But that's my situation. I'm changing to manuals on that thing when i get the cash, no more auto's for me. My ranger has manuals, i don't mind getting out and locking them in if it gives me better gas mileage, and it gives me the comfort in knowing that it is in 4 wheel drive once the tranny case is in 4x4.

All of the auto hubs that I have had experience with have failed. Never had any failure with manual hubs.
Just to clarify things, an auto hub is not locked in all of the time. It only locks in when you put it in 4x4 and the axle shaft begins to turn which locks the mechanism in the hub.
Full time is locked in all of the time.

"Your Chevy didn't have hubs at all, it had a locking differential. That's why they didn't go bad. The CV axle stub was splined stright to your spindle with a spindle hub nut"
No it did have locking hubs. It was a 1990. The suburbans and k5 blazers didnt change over to independent suspension till 1992. The trucks did in 1987.
I had a gm 10 bolt solid axle. I know they were locking hubs cuz i had to tear them apart when i replaced the rotors. There was no locking differential. And no cv axles.

Ok, blanket statement...I am wrong for this statement.
I have a pile of broken auto hubs from explorer's/bronco II's from '91-'94. Like numbering over 100 pairs. They are supposed to be able to engage at up to 55mph, most ground or skipped before they were replaced with new Warn locking hubs. I have close to that number of F-150/Bronco auto hubs as well. Most all of these the customers asked to replace the hub, rather than being diagnosed.
I was wrong about the chevy...sorry...wrong year.
I will not state that ALL auto hubs fail....just a huge majority....hows that? I feel better.
