I just installed an ox and upgraded to 4.11 in the rear. Now I need to do the same (the gear ratio) to the front so I can use 4wd.

I've come to find out that it is so hard to find gears that are 4.11 for front D30 axle. Almost all of them are 4.10


as you can see I am a newbie, and I'm not sure if it would bad or will i experience skipping of front wheels if I put 4.10 in the front (with 4.11 in rear) or is the difference neglectable?

Thank you.

Run it, you won't feel nothing, loose surface will absorve any difference.
Permisibilty should be around 2%.
4.10 to 4.11 is aorund 0.2%

For what it's worth, most factory rigs don't have exactly the same ratio front and rear. By the time you factor in drivetrain backlash I don't think 4.10 versus 4.11 would even be measurable at the wheel under any circumstances.
