4.56 gear install

[farmer]

I just bought used 4.56 gears for my project truck, and I was quoted $200 an axle to have them installed. Needless to say I'm going to attempt to do it on my own. I've read the Yukon install several times now, does anyone have tips, helpful experience, or at least $.02 to add to help this go smoothly? Thanks

Yeah, read it again...After you read that, read the one in the tech library...It's not as hard as some make it out to be, but just take your time and do it right!!

The yukon install in the tech library? That's the one I've been reading. It doesn't seem too bad, but I've had alot of people try to talk me out of it

Used gears? Do you know the backlash specs of the diff that they came out of? You can ball park it using the used gear specs, but you'd be alot better off if yoyu had the specs from before they were taken out.

For $200 per axle to have them installed? Do it! That's cheap for a gear install!

I have read those and more. The one thing I found in reading is to take your measurements before you disasseble the diff. Once you remove the ring, clamp a piece of metal to the back of the diff and measure the and measure the pinion depth. Also each time you take it apart and put it back together. Use the old.old crush sleeve . Check your measurements, check your pattern on the teeth, Then use a new crush sleeve for final setup.
Another thing I read was that if you start with the shims that come from the factory you will be right on about 70% of the time.
These are thing that I have read, and are free, so take them for what they are worth. Good luck

This. $200 an axle is way cheap, especially on a front axle.

Yup.

But if you think you still want to try it yourself, there's more links to gear setup stuff in the Axles FAQ right up at the top here.
