I'm thinking there is still/we need to pin down whats worn/binding that is causing the issue then lube it (unless it is strickly a dry/no lube issue that is causing this & I'm doubtful). I would want some lube that is at least semi viscous so it flows to every crevice. IIRC used some gear oil as is one time way back & it did not leak out the bottom seal. Ebergs' concoction, he melted some good Mopar grease in the tube (it was green) in a saucepan & added several ounces of gear oil (iirc) so it would flow.
