Gear installation

[njonl]

I recently got ahold of a 12 bolt with 4.56's and a locker. The guy that had it before me said he was in a rush and he just threw the gears in there without setting them up. I am very interested in learning how to set up the gears on my own. Does anybody know of a good resource or a good book in which I can learn how to do this ? Thanks!

Before you actually buy anything yet , pull the cover , spray her clean with Brakleen , and apply the yellow marking compound .

You may get lucky and have a decent pattern . Post up a pic of the pattern .

Did the guy say whether it made a lot of noise or not ?

If the gears weren't setup right and were run for any amount of time they are probably ruined and can never be setup right.

I've setup ~2 dozen diffs and have rarely had one use the stock shims. If the ratio is the same, the pinion depth is usually the same. If the ratio is different (like in your case) it almost never is. Backlash has almost always been different for me.

Here is a link to how to setup diffs:

You can take a pattern (as per the above link) and post it here. We will try and help you the best we can but I honestly think that (if its been run) you need a new gearset.

Sorry I should have clarified. He never ran the gears as they are now. He had it apart in a friends garage and then he had a baby. So they sat in the friends garage for a long time until the friend needed the garage space. So he just threw them together real quick to be able to move the axle. I will see what the pattern looks like. Thanks for the link!

There's a pretty good discussion of gear installation at:

I suggest you use the "Search ColoradoK5.com" tool at the top of the page,
and I'm sure you'll find all the information you could want on this site in
prior discussions.

Oh , if its never been ran then , you can get the install kit and do it . I had the opportunity to have a gear guy help me , and although you need a few tools you may not have , its not very hard to do .

Mine made me happy

eh tools are tools. I've setup a 9" with nothing but a air gun and torque wrench, rebuilt a th350 with a large screw driver, a hammer, and a set of pliers, rebuilt a sm465 with most of the same. Of course, on the 465 I had to take it to a shop to pull off the last bushing. Stupid thing sitting on a lip. The right tools sure make everything easier, but don't be scared just because you don't call the snap-on guy by name. Try it out with what you have. If you do indeed need a double jointed 3.4765" monkey nut remover, go get one. Or call up your buddy and borrow his. Buddies always have monkey nut removers for some reason. Gears are a heck of a lot easier than they're given credit for. 9" is probably the easiest, but everything else is just shimming right.
