    Just as the title says. Your experiences. These would be for a D60 and I'm gona beat the crap out of it. Are they any stronger or weaker than a regular locking hub. Drive flanges are not an option.

    I don't think they are. Both of the 10 bolts that have been under my truck have had them and didn't work right. I replaced both sets with Warn standard lock outs. Never seen autos on a 60 though. /forums/images/graemlins/thinking.gif

    My DD has them but I don't offroad that one. Don't know about durability. Maybe somebody else has tried them.

    Hell yes they are good...... If you clean them up, the outside cover thay says 4X4 makes a pretty cool paper weight. /forums/images/graemlins/thumb.gif

    my overall experiences with auto hubs has been mixed-

    Sometimes, they have been cool, like, it starts snowing, hard, you switch to 4x4, and keep going. When you need to switch out, you just stop, and put it into 2x4.

    However, I've been stuck in a k5, with auto hubs before, cause the uato hubs wouldnt engage. Looked f'in hilarious on the side of the road with a k5 stuck in 3" of snow cause the stinkin 4wd wouldnt engage.

    You give up some of the convenience, but you add tons of durability. I've also heard that sometimes the auto hubs dont work in reverse. Would be a terrible effect offroad.

    If this tells you anything, according to the parts manual, GM tried auto hubs in the '85 1 tons, and from '86-88 they were no longer available, only manual hubs.

    Not true.
    They unlock if you go reverse with the T case in 2wd only.
    If you have it in 4wd they do not unlock.

    I don't like the auto hubs anyway because they are weak and problematic, I would keep them on a DD but not on a trail machine, even if it's driven to the trails and used daily.
    I would only keep them on a stock vehicle that will not see anything more than a dirt road to a campsite.

    When you expect snow, just lock your manual hubs before you go and leave the T-case in 2HI. Then you can pull the shifter between 2HI and 4HI as many times as you want while still moving. You don't even have to back up to unlock the hubs. This doesn't really put too much wear on the front end, unless you do it all the time. That's how some new trucks are set up.

    My auto hubs are perfect and sometimes I think about swapping them back in for general winter driving, but since going to manuals, I really haven't missed the autos.

    For me , yes. I have had my blazer for 16 years and it has auto hubs. Still use them and just used them over this last weekend 4 wheeling. Never had a problem. I use the 4 wheel drive an average of 20 times a month; driving on sand with the bed full of SCUBA tanks (a lot of serious weight carrying 32 tanks while driving on the beach!) use it in the bush and rock crawling up river beds. Again, never had a problem. I do preventive maintenance every year; R/R the hubs, grease them up and install new seals. Just lucky I guess using mine. I've shifted back and forth from 4 H to 4 L with no problems. Once I hit pavement, I put it back in 2, back up about 30 feet and drive off.

    I suppose you have stock size tires?

    Well in my post I said dirt, sand is even easier on the axles, so yes they should be fine.
    That is what these hubs were designed for, mild use, not what we subject them to in the rock crawling.

    I got a call to go pull my buddies out of the sand and my autos wouldnt engage. Pretty emberassing being pulled out by a s10 when you were brought out to save ppl. So when I got home I ordered some milemarker locking hubs. 53$ at this website I found.

    Mine failed on a boat ramp while I was trying to pull a 10,000 lb boat out of the water. /forums/images/graemlins/smile.gif This was when I worked at the marina and it was a customer's boat. Hitched up to it, backed trailer in, buddy pulled boat up onto trailier. I put it in four low, step on the gas and start spinning both back tires. Those were the days when I had 2.73 gears and I had a gov loc that worked so it was pretty funny. /forums/images/graemlins/smile.gif Spun the back tires for like 10 seconds and then it slammed into 4wd and ripped that boat out of the water.

    I went home from work and ordered Warn Premiums. I have never looked back. I honestly wanted to keep my auto hubs because they're perfect for lazy asses like me. But getting stuck in your own yard or on the boat ramp is just nonsense....NEVER again.

    Got done R&R'ing mine (never had a problem, just wanted to make sure they were in top shape), went out after R&R on them, tested, worked fine, took them up to the mountains for hunting, first place I needed them they wouldn't engage. Typical ratcheting noise from the front axle, spun the rear tires at about 2000RPM before the hubs locked in. 31's with a 305.

    Lucky I didn't break anything, but that was the last time I EVER trusted auto hubs. Manual hubs have NEVER let me down, even 25 year old factory ones.

    My old K30 had them stock, they failed under normal use (stock tires / occasional 4x4).
