    Hey all,

    My '88 has Automatic hubs, they lock when the axles are rotated by the driveshaft, not the wheel. I'm not really into them, but they work, and they don't seem to be sticking when I come out of 4wd.
    I want to switch to manual hubs. A place here has Warn hubs for my truck for $59, and it looks like the complete hub assembly. Another place has the hubs for $89, and they insist I need a $70 conversion kit. I'm not into the thought of having a kit to be an added weak link in my hubs, and I don't understand why it's necessary if I have a complete manual assembly to put in. Auto hubs can't use different axles or rotors, can they??
    Do I really need this conversion kit or is it sales? I know others on this board MUST have done this before. What does the kit consist of?

    BTW, thanks all for the brace tips...

    I did the auto to manual switch about 9 months ago on my 89. it was a easy swap and did not need the conversion kit. the conversion kit is only needed if you have FULL TIME 4x4. If you have auto hubs, you dont have full time 4x4.
    I used Superwinch hubs on mine and have done a lot of wheeling with no problems. But people on this board have had problems with them if they have a locker up front. They say the warn hubs are better.So you might want to go with them. Either way it is a pretty easy install.I just removed the old auto hub assembly and replaced it with the manual hubs it took less than 1 hour to do.No rotor change or axel mods. I am much happier with the manual hubs than the autos.

    You shouldn't need any conversion kit. I would recomend warns premium hubs. They will cost you about $70.00, but you will never have to worry about them again.

    Yes, get the Warn Premiums! It's a little extra money but worth it for the all metal construction (vs. some plastic in the standards). And NO, you don't need the "conversion kit", unless you have full time 4WD (as in 203 case) OR (and this is a note in the Warn Catalog) you have the "Automatic 3-Hole Cap Screw Hubs", then you would need the Spindle Nut Conversion Kit which is part number 32720.

    Otherwise just get the Warn 20990 Premium Hubs...

    The Warn Premium hubs are really easy to install (About 10 min. for both sides) and they have a full warranty for breakage! I got mine in May and love'em (see pic at link below)
