    I've got a '91 Jimmy, and my automatic hubs are gonna go. I am buying warn manual locking hubs probably this weekend some time, but then i saw a conversion kit. Do i need this conversion kit to swap in the manuals for the automatics? Or will the manuals go right in without the kit?
    Thanks,
    Tony

    No you dont need the conversion kit. The conversion kit is for rigs with full time 4x4.All you need to do is just pull the old hubs and instal the manuals.

    Ok, i ordered a set of premium manuals from warn, and i should be getting them on monday. Can anyone give me an idea of what im going to be getting into? Ive heard that it should only take an hour for both sides, but what exactly do i have to remove and put back in?

    Took me 5 miutes per side.

    Here's what you do...

    1. Remove the 6(?) screws that hold the hub in place.
    2. You will find a clip holding the ends of the retainer ring in the hub assembly. Remove this clip thingy and then, using needle nose pliers, remove the big retainer from the hub housing.
    3. Now, I can't rmember at this point. But there is a retaining ring in the axle shaft itself. You will need retainer pliers to get it out (or it makes it easier). I can't recall off the top of my head if you remove that then pull out the hub gear assembly or vice versa. But you will see it.

    Now you should have nothing showing but the spindle nuts, the threaded spindle, and the axleshaft.

    Now for assembly....

    1. Clean any grease out of the hub splines as it will interfere with the warn assembly.
    2. Insert the Warn gear assembly.
    3. Insert the new retaining ring from Warn that pops into the hub itself. I highly recommend bending the ends of this ring. It will make later removal much easier.
    4. Make sure the outer hub is unlocked and screw it onto the hub using the screws provided.

    Voila. You are done. Take you more than 15 minutes per side and your are probably doing something wrong.

    BTW, after I first installed mine, I tried to lock the hubs. They were very difficult to spin after they made it to about 2/3 locked. And they didn't "pop" locked like they did unlocked. But don't worry, this is normal. After a little use, they lock and unlock freely now. And, if they don't pop locked, they do as soon as the vehicles begins to move.

    quote:"clean the grease out of the hub splines...."

    Better leave some grease in there. If you don't they are going to be a real bear to remove next time. I know Warn says you don't need any extra grease but if you ever drive through water this ain't the case. Better yet, replace the grease with anti-seize.

    tx85GMCguy,

    Very good post. I'd also like to add:

    MAKE SURE YOU REMOVE EVERY SINGLE PIECE OF THOSE WORTHLESS AUTOMATIC HUBS. I've taken apart some really weird combos of snap rings in there. All you need is the big one that holds in the hub assembly.

    And yes, make sure you bend those snap rings or they're a nightmare to remove. I thought I was the only one who'd come up with that idea (after spending up to 45 mintues picking that damn ring out before).

    It only took me about 10 minutes to do the automatic to manual conversion, and it was one of the best things I've ever done to my truck IMO.

    Wasn't that long ago that I was a NEWBIE. I am just glad I can offer assistance. Its always neat to have someone ask a question about something you, too, have done. You can then tell them what they need to know and sound like an expert! LOL! You will always be a newbie until you try things yourself. Then, you, too, can help those on the path behind you! But we should never forget that we once forged along that same path ourselves!

    You can get a cheap set of picks at any parts store for bucks. It only takes a few seconds to pull the hub ring with them, and they come in handy for other things.
    If you look at the ends of the ring on is angled toward the hub and on away. Hold your allen wrench against the end angled towards the hub and pull the other end up and out with the pick.

    If you jack it up, leave the tire on the ground. I never jacked mine up, though. Hell, didn't even move it into the driveway! Did it in the street next to the curb!

    Thanks very much everyone! Got the hubs in, took maybe 25 mintues total. Found a busted bearing in both of the automatics (probably why i had a problem getting into and out of 4 wheel) Just wanted to say thanks!
