Actually, putting the stuff back in is easy once you figure out the process. However, there is little more than 12 square inches of free space to move your body around in when not using a lift. I thought about breaking my forearm in two additional places so that I could get more manual articultion. I figured out the purpose for that second "hole" in the rear of the carrier. It is for the placing of the small convex "washer" that you slip under the spider gear. Spider gears go in first "naked". That is, without the convex washers underneath them.
From what I could tell, the ONLY way to put the gears back in is AFTER one puts in the axles. It does not work in any other fashion. I tried.
Yes, I knew it was somewhere in the diff, not the axles or drive shatf where the problem was.
Anyway, I learned alot from this experience which is one of my objectives for having a cruiser.
