    4WPW Did The 4.56s And Lockers On My 82. They Will Not Warranty These Gears With 35 Inch Tires.I Would Not Attempt To Replace Them Myself . If They Are Not Set Right You Will Destroy Them Real Quick . Also They Will Not Warranty For Improper Setup If You Do It Yourself. So I Did It The Easy Way And Let 4WPW Do The Work.

    Replacing gears is a long, tedious, and tough task for someone who hasn't done it before. I am kinda refreshing myself on it as it has been since tech school since I've setup a rear. Unless you can do dang near anything on your truck it may be time to farm that job out. That or try and find some axles for sale w/ the gears you want

    I have done a lot of research on this. As far as installing them, I wouldn't do it yourself. If your gears fail due to installation, you may have to fight about that warranty. And, even if they did cover it, you don't want to be sitting disabled because your diff just grenaded. The going rate around here is about $300 per axle install. You might be able to find a mechanic in your area through here or a friend that would do it cheaper and let you help so you learn. That's what I am doing.

    As far as where to buy, I shopped around a lot and found I got the best service and information from <a target="_blank" href=http://www.ring-pinion.com>Randy's Ring &amp; Pinion</a>. They really knew there stuff about which was best and what all you need (install kits and such). I just got a set of 4.56s, two install kits, and two Detroit Lockers from them last week.

    Good luck!
