In my experience, it takes longer than 5 min to pull a shaft on a D30, especially if the axle hasn't been gone through in a while, but that is besides the point. Aside from the weak housing and the smallish ring and pinion gears, my biggest gripe with the D30 is that it is not even a full floating axle, it is a semi-floater. If you pull the stub shafts out of a unit bearing D30, the unit bearings will fall apart, and your wheels will fall off. 
If you are going to do it, do it right. A D30 is a step backwards, they might survive under 3,500# rigs, but were never intended under a 4,500# supercab Ranger. D44's work for some people for reasons already mentioned; but IMHO you aren't gaining a lot. If you can at all afford it, go with D60's.
