Since taking mine apart, I know that even with a hole drilled anywhere you want it, you absolutely can not properly lubricate everything that need it without a dis-assembly. Plus the complete dis-assembly is not a chore.
Two screws remove the motor assembly. One plastic plug and the "shift" lever removes the nylon motor socket "clutch", and one "E" clip removes the manual drive socket and the top gear. Lift the bottom gear out and a roll pin slipped out releases the entire lower telescoping section.
I then removed the 6 screws to remove the top motor/gear housing and greased all of the gears in the top gear assembly.
I used a small tub of Liquid Wrench white lithium grease that I bought from Carquest. That is some sticky grease. It will surely outlast whatever the factory used.
I spent about 30 minutes per jack and I now have complete confidence in my jacks. I would also be very comfortable dis-assembling one if a failure should occur while traveling.
