Started servicing the Happi-Jac electric jacks. They are 8 years old, and in pretty good shape internally. A few rock chips on the legs. So I am re-lubing, sanding and painting. Here are the picts from the rear jacks, 4150's.

The end of the lead screw.

I used a short extension on a cordless drill to run the lead screw in and out as I lubed it with waterproof wheelbearing grease.

The tube just above the end bearing. There is a seal there that keep moisture out.
