    I've read a couple write-ups on Detroit locker installs in 14 bolt FF's and it sounds as though it's pretty much a cakewalk as long as you put everything back in exactly as it came out. i.e. bearing caps on the correct side, bolts tightened the same # of turns, ect. But what if you've got a posi carrier and your replacing it with an open carrier from a different diff? Wouldn't the new carrier/ring&pinion need to be set up (lash set .ect) since its never been in this axle housing? Or is it still a bolt in operation?

    TIA,
    Jack

    you can bolt it in ethier way, but with new gears or carrier you have to get out the guages and what not
    just to make sure. i know a few people who can install carriers all day and do it all by feel. then turn around and say, 2 year warenty.
    i cant. some day

    <font color=blue>I just took the peices of a gov-loc out of my 14 and put in a detroit a few days ago. The open carrier I bought with my detroit had new bearings on, so I had to start over with the backlash. You have to set the bearing preload first, then adjust the backlash. The manual calls for .003-.012" of backlash with .005-.008" being optimal. I set mine at .007". If you want, I can try to dig up the instructions I printed out from Alldata.

    Thanks Chris, that's what I figured I'd have to do but wasn't sure. I'd appreciate the instructions too, I need all the help I can get. I've read that it's a 2 man job to set the preload &amp; backlash. Did you find a trick to do it yourself or did you have help? Do you mind if I asked where you got your locker/carrier and what it set you back?

    THX,
    Jack
