Right after getting the Power Steering installed we took the Jeep for a test drive.  The power steering worked great!  I pulled out on the main road (Renee was following in another vehicle just in case) and the Rear drive shaft sheared one of the bolts at the Pinion Yoke!  Great, another project...  We had to pull the shaft out of the tranfer and put it in four wheel drive to drive it back under the power of the front wheels only.  Parts are on the way.
