Many thanks to KKELLER14K. This is a most excellent thread. My problem was not related to lube or lack thereof. I had no broken or worn gears. The jack simply froze up and could not be extended or retracted with the motor or the manual crank. After removing the motor and top gears, the inside telescoping part containing the acme threaded rod would not budge. It finally took several minutes with a 6 lb. hammer being applied to the lower jack foot to remove the inner jack assembly.
Slivers of black paint that had been skimmed off of the jack and tightly compacted between the two sections had virtually welded the two pieces together. I then disassembled and lubed the other three jacks and none of them had any paint buildup.
Thanks to this topic, I am now very comfortable completely disassembling/reassembling the jack units. I also copied the tutorial and filed it with the owners manual for any future reference.
