4.11 front 4.10 rear

I've got my eye on a 4.11 d44 front axle for a swap in my CJ, the rear I will be using comes out of a rodeo its a d44 geared at 4.10. I have read through some forums and most people say its "close enough", but I wanted some input here.
Is running a 4.11 in front and a 4.10 in back going to cause me problems?
Thanks.

It will be fine. Old Bronco's came that way from the factory.

You can use any combination of 4.11, 4.10 and 4.09 together front or rear. As long as the ratios are within 1% of each other they work together.

Your difference is only 0.2% ((4.11-4.10)/4.10). Your tires can be further off than that with one having different pressure than the others.

Also I saw on the tv show on spike called Xtreme 4x4 that it's fine and they did it.

I wouldn't take a program on spike as the absolute truth...

We run in the sand, but we intentionally stagger the gearing. I run 4.88 rears/4.56 fronts. Dad runs 5.38 rear/4.88 front.

What are the benefits of this, and is it only in sand? Also, does it matter which is taller? Front, or Back?

Because an auto repair program on spike TV is in the business of selling you something.

I believe the front tires spinning faster helps with steering in sand.
