    Does anyone know the correct preload to set on the drum for a Corp. 14 bolt FF rear axle?

    I am replacing some seals in the 14 bolt I got recently, and need this figure to put it back together.

    Thanks,

    Thomas.

    While rotateing wheel tighten adjusting nut to 50 ft-lbs
    Back nut off until nut slot lines up with key way and install key
    On models with nut lock bend the square tang over the slot
    Install lock nut.

    From my Haynes Manual

    Thanks Bigd, I appreciate the info.

    I've got one of those manuals, but it's for my blazer. I guess I'll need to get one for a 3/4 ton pickup, or maybe a suburban?

    Thomas.

    <font color=blue>I like to set bearing preload by feel. No two bearings are exactly alike, so torque specs are vauge but they're a good starting point. I try to wobble the hub on the spindle as I tighten it. When I fell there is no wobble play, I rotate the hub while tightening until I fell a just little drag, then I tighten it until that little rectangle thing lines up. Oh yeah, that bearing seal is a pain. I fought with a prybar for 20 minutes then I set the hub in a bench vise and used a slide hammer. Worked first time on both hubs. Just make sure you get something to catch the bearing with so you dont damage it.
