    91 Jimmy with stock drivetrain. I am going to replace my stock auto hubs with either Warn or Mile Marker manual hubs. Warns website says that I need an Automatic to Manual Hub Conversion Kit. Do I need this? What does it do? /forums/images/graemlins/thinking.gif

    No you don't need it. I'm not sure what it does. I put Warn Premiums in years ago on my 89 so bare with me. I believe there's a washer next to the outer locknut that you throw away and then there's a small snap ring that goes outside of that (keep the snap ring). The reason for not using the washer is because the Warn hub will stick out a little too far with it in there. Just take out your auto hub, put in the Warn hub and then put the snap ring on the outermost groove of the axle stub. Should take you about 15 mins per side if you're slow.

    I put the warn premiums on ny 90 blazer and u don't need any other kits. Just pull the autos out and replace them w/the manuals. They work great and I've never had any problems with them.

    I have the Warn hubs on my Blazer and the MileMarker hubs on my '56. I like them both as long as they are the premium hubs. I did need new bolts for the Warns a couple of years ago and Warn sent them to me for free. I'm not too sure about the MileMarker customer service since I've never had a problem with them. /forums/images/graemlins/cool.gif

    just out of curiosity...why change the hubs? I've had no trouble with my '91 auto ones. Is there something I should know about?!!

    They're weaker than manual hubs and more prone to something going wrong because of all the internals.

    There's a chance they won't engage when you need them most.

    There's a chance they won't unlock when you want them to.

    Overall, if you don't hammer it offroad much, they should be fine. When they do break or fail to work, though, replace them with manual hubs.
