    Yep, simple as can be.

    1) remove axle shafts
    2) pull cover
    3) Remove 2 prong locks on screw adjusters
    4) Mark bearing caps Left and Right
    5) Record backlash on gears
    6) Back off the screw adjusters and remember how many turns you did it, say 4 turns per adjuster
    7) Remove bearing caps
    8) Pull carrier out and remove ring gear bolts
    9) Seperate carrier halves and remove spider gears and install detroit
    10) Bolt halves back together and remove the wing nut and bolt and washers from the detroit
    11) Reinstall carrier into diff and install bearing caps
    12) Tigthen screw adjusters same amount of turns you loosened them and check backlash
    13) If backlash is correct install the 2 prong lock thingies
    14) Reinstall cover and axle shafts and fill with gear lube and enjoy your inreased traction and tire wear

    At step 9 in Jason's instructions there is one more thing to watch. YOU HAVE TO MAKE SURE THAT YOU REMOVE ALL OF THE THRUST WASHERS FROM THE CARRIER AFTER YOU REMOVE THE SPIDER GEARS AND SIDE GEARS. There is a spherical washer on each spider gear (these are hard to miss). There is also a thrust washer in each side of the carrier between it and the side gears. These two thrust washers will stick in the carrier, and they are easy to miss. If you do not remove these two washers, the carrier will go back together with the DL installed, but the locker will never unlock.

    I have a question about step 5 and step 12. According to all of the websites I have seen, they say the detroit can be installed with simple hand tools in a couple of hours. But, doesnt checking the backlash require special tools just like a ring and pinion setup? Or will the backlash be back to normal as long as you count the number of times you turned the screw adjusters. Thanks.
