Default Gear ratios

was wondering if putting a 3.45 gear in the rear with a 3.55 in the front would hurt the 4x4? My rear diff has a lot of play and wines driving down the road and I have an 8.8 ford rear out of an ‘89 ranger that I was thinking of swapping in it. Just don’t know if it’s that big a difference between the two

The front and rear have to be the same, if you meant 3.54 then that would be fine to use.
