Yes and no, in 1974 in a Dodge Power Wagon, Dodge used a 4:10 for the rear and a 4:09 for the front. It was done this way to compensate for ware. So given those facts one could say it is conceivable. But maybe not practical now-a-days due to the close tolerances that gears are now made, and dealing with what we now travel over offroading. I still say sure, why not.

GROWING OLDER IS MANDATORY, GROWING UP IS OPTIONAL TREAD LIGHTLY

it should work fine. having a numerically lower ratio in front is actually better than having a numerically lower ratio in the back because in 4wd the front wheels turn (just SLIGHTLY) faster causing a nice pulling along affect. and it helps with steering in 4wd.

i have an 8.8 rear w/ 4.10's and a 4cyl d30 up front w/ stock 4.11's. being that you only really use 4wd when the roads are slippy, or for offroading, that small of a difference is not noticeable b/c the wheels are slipping anyway over the uneven terrain....i wouldn't advise any more difference than that, but my setup works just fine

Do you live in an area where you will use 4WD on the street?

Will either of these have lockers?

any ratio within about 2% variance will work. 3.54/3.55, 4.10/4.11 etc.

This is true... 4.10/4.11 is how they come from the factory.

JUST RUN THEM
you will be fine they are off by one hundreth of a ratio
that is nothing. thats like saying that if you have brand new tires on the rear axle and one week old tires on the front axle then it wont work.
dont worry so much run that set up and you will be fine
