Ultra - Reading in other forums, someone said they called Lippert at the same point as you are, and Lippert told him to "learn to live with it". What is happening is stiction, and this link (which I was too tired to find last night) mentions specifically one quart, but also says "follow the instructions" (who does that ?) Good luck with it.

Incidentally, I did change out 1/2 of my hydraulic fluid for the Type A that is recommended. Had to purchase it from Amazon - it is synthetic whale oil. The one quart of Cat stuff I added did the job for us. I never heard a 'pop' again. I don't know if the Type A made a difference for me or not. But I kind of doubt many people make the effort to find synthetic whale oil.
