    Does anyone have info on these rears? Vehicle GVW is approx 21,000+. They are Rockwell axles from a 1980's Ford F600 4x4. They have large 15.5" drum brakes, square tube housings, front loader type gears (6.80 ratio), & large 6 bolt wheels. I believe they were model ZF56 (didn't have anything to write the info on at the time) Can anyone positively identify these, & does anyone have info as far as durability, value etc. Looks like good material for a serious offroad buildup. Hate to pass up a good deal. Thanks for any info you can contribute.

    Maybe that will help a little.

    Chad,
    Thanks for the info. I reviewed the links above &amp; got some good ideas...... the axles I saw today are not 2.5 ton Rockwells. The hubs look like the 2.5 ton units as well as the axle tubes, but the links you provided of 2.5 ton units show a top loader type axle, whereas the ones I saw are front loading (as is a 9" Ford rear) Can anyone identify these? They are often used in plow trucks &amp; some of the forestry vehicles. Unfortunately I know little about them.

    Sorry about that... I noticed you said front loading after I posted all the stuff. There are 2.5 ton front loaders but I'm not sure that they are rockwells. I know people like the top loaders because of the good driveline angles but I'm not sure how they compare in strength. You could probably find more info on Rockwell's at Pirate4x4.
