    Are there any draw backs to self locking hubs?

    From what I've heard is that sometimes they don't dis engage all the time when you want them to, or it takes a moment for them, or one will and the other won't etc.....

    Are you talking about the auto locking hubs that come on later model Blazers?

    The ones on my '90 K5 worked fine for about 110,000 miles. Then they started screwing up and trying to engage by themselves while I was driving. They have now been replaced by a set of manual Warn hubs.

    I have heard that the auto locking hubs are a weaker design than internal spline manual hubs, but I'm not sure about this.

    Later!

    I thought I heard that same thing, thats why I wanted ya'lls input. The guy said they are new and he just installed them....(funny that doesn't explain the rust on the covers..heheh) I think he meant internally they are new. Actually the guy didn't know what the heck he was talking about. Oh well... sounds like it needs some WARN Manuals on it.

    I had the stock auto locking hubs on my Jimmy when I bought it. They worked fine for a while then they started "unlocking" when I really needed them.. So I tossed the to the side and bought some Spicer units.... I really like these, the internal gears are really stout. But the Warns go together easier, my borther just bought a set and they just slide in and pop the lock ring in and you are done.

    YES!!!!!

    CHANGE THEM! I won't go into the whole spill, but like the other guy said, when they wear, they cause BIG problems. Cheap insurance, go ahead and get the WARN's. You'll be sorry the first time the auto's lock when ya don't want them too, TRUST ME!!! I was!

    ok...I am still a newbie when it comes to stuff......
    How hard is it to change a set of Auto locking hubs to manual hubs? I am looking at a K5 and that was the only drawback I saw to it....Auto hubs just don't fly!!!

    They are a piece of cake, helped a buddy of mine put in a set, took very very little effort. Although, my 85' with 177,000 auto hubs have held up fine. But when they do go Ill replace like the rest of you...

    Id have to say scrap the autos too. They are too easy to change out and very inexpensive. I changed my auto hubs twice before i got smart and went with the manuals. I heard that Warn are the best, but I went with Superwinch and have had no problems and have been very pleased.

    I've got the '79 w/ full-time 4WD. Wondering if I should go w/the Part-Time kit and manual hubs. I haven't had any problems yet, but wonder if f/t 4wd is also more likely to have problems.

    Thanks,

  14. My 82 had autolocking hubs when I bought it.One was locked up,and the other wouldnt engage.I took them apart to see what was wrong,some of the internals are plastic!!!I went to the dealer to price two parts that were bad,these two little parts were $70!!Warens were $80,but you have to use a adapter kit to use them because the spindle nut wont let if clear.The kit is $45,but its worth the money knowing when I engage my hubs there are no plastic in there to reliy on!!!

    IF IT AINT BIG IT AINT BAD!!!!!!

    Hey 79Guy, I would go with the part-time kit and manual hubs. It'll pay for itself in improved gas mileage and reduced wear on the drivetrain. Just my 2 cents

    They reallly area apiece of cake. They are already greased and everything. YOU simply take out the old ones, slide the new ones right in, the directions are very helpful. No need to gease them b/c they are greased. Dude, any guy can do it.

    Yup they are pretty easy. There are 6 allen head screws on the outside, all you have to do to get the cover off is undo these. Then to get the auto lock out in the front there is a snap ring that you can get our with a pair of needle nose and then you slide the hub out. Then you put the new up in, put in the retaining ring, tighten the 6 hex screws on the new unit and your done. Hope this helps. Doug Krebs
