Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

Generally speaking, if your jacks are hydraulic, and are not acting properly, lubrication per se is not what is required.

A: check for hydraulic fluid (thin but oily) leakage.

B: What exact model is this? and is it in a stand, or add-on which has the jacks?

Lubrication in the sense of oiling or greasing is not likely to be required. Unless what you call 'jacks' are something else.
