Are you talking about swapping the entire axle assemblies (not just the gears)?

If so, if the '94 axle(s) have ABS, I don't think the ABS would function anymore, but I don't think it would be a big deal.

Check to see if the rear pinion ujoint is different as well.

I swapped a 1994 D30 into my 1990, no issues. I used my old vac disconnect motor because the hookup is different on the newer versions.

Front brake lines are different and you will have to move the 94's to the 89. The rear brake flex line is different too, almost forgot about that. Of course you know or will find out that the front and rear brakes are entirely different and none of the parts interchange. I just did a 95 to 89 swap and that was all it took though as far as swapping the axles.
