Thank you, the other side is much fuller than the level indicated in the document. I have had not issues with that side. Suspect I need to order a new center plug, but when I pulled it out to add lubricant, it did not seem hard, and it has not leaked since I added fluid last week. I have to do the air dryer tomorrow, I will check for leakage then and see how it's level is.
