littlebuddie,
In regards to your 'is it feasible' question. The trick is to raise the truck and put it on jack stands (under the frame), but only take it up far enough to have the front wheels off the ground several inches. You then take your floor jack, put it under the center of the axle and raise that...remove the u-bolts, then lower it the few inches back onto the wheels.
The springs are now dangling and can be easily removed. Reverse the procedure, and viola...take a spin.
Be sure to wire brush the threaded portion of the u-bolts and coat them with Never-Seize before you remove them...those fine threads can self destruct with a long cheater bar oinking on them.
