    Sort of a dumb question but...I've got the stock automatic hubs...never had a problem with them. I decided I'd get some warn manual hubs when my auto stock hubs went out. How can you tell when your hubs go out? I mean if both go at the same time...I'm sure you could feel it...but explain it. If I went outside and wanted to check...could I just crawl underneath and turn the front driveshaft or what? If the transfer case is not egaged in 4x4 should I be able to freely rotate my front drive shaft?

    You dont want to find out the hard way when they are not working together. That would be the more expensive route. Just sue an extra person today and go buy a set. /forums/images/icons/grin.gif

    since you dont have them yet just go get a set of warn premiums they are only about $10 more than the regular warns and just put them in and junk the auto hubs /forums/images/icons/smile.gif

    When mine "failed" (which was never very consistent) the truck, when the hubs SHOULD have been locked in, amde a buzzing noise consistent with engine RPM.

    Typically this noise occurred when the truck was sitting at the bottom of a creek bed, attempting to climb out, or when there was snow on the road, but no problems on flat, open, dry dirt paths. (where you don't even need them)

    I went to the wrecking yard and grabbed some factory spicer manual hubs from an earlier 4wd truck. Bolt on, and good quality. Cheap too lol.
