    I want to re-gear my front 10 bolt from 3.42 to 4.56. I may do it myself, but if it looks to hard I will probably let a shop do it. Does anyone know what a shop might charge to put 4.56 gears into a front 10 bolt? Also, if anyone on here has a front 10 bolt for sale with 4.56's for around $150, let me know. Thanks.

    You can probably count on about $50-80/hr. I dont know how long it would take to do it, but I'm guessing probably atleast about 2 hrs. The best thing would be to call around and find out, only the shop that's gonna do it can tell you how much they will charge.

    It may be cheaper for you to buy the parts and then find someone to put the gears in /forums/images/graemlins/truck.gif

    Its not difficult, just very, very time consuming. Not to mention it is very tedious work. If you have access to alot of measuring tools, (i.e., calipers, dial indicators etc.) then give it a shot. If you don't have alot of free time then let someone else do it. /forums/images/graemlins/ears.gif

    I re-geared my front 10 bolt in about 8 hours. We took a lot of breaks...anyway, the hardest part is crushing the crush sleeve. Get the longest breaker bar you can and jump on it and it'll slowly turn. A shop press wouldn't hurt and a bearing puller would be nice too.

    You are joking about finding a 10-bolt front with 4.56s for $150, right?!? The gears alone with an install kit will run that. Gears alone run around $100. A COMPLETE install kit should run another $75-85. You can do it yourself, but will need various specialty tools and a lot of patience. Gears aren't that hard, but do require precision. If not, they won't last long and all your work becomes for not. Then again, doing it yourself teaches you a lot about what is going on inside the axle making it easier to troubleshoot a problem later when you may be 20 miles form the nearest pavement!

    Going rate around here for gear install alone (no parts) is around $350 for a front axle and $250-300 for the rear. You are planning to re-gear both, aren't you?
