Lippert 6 point leveling system

Briefly, Lippert paints their jacks black. This easily masks minor weeps and seeps of fluid leakage. You need to clean up the jack top to bottom (I use brake clean). Then have someone run the jack up and down and you can watch the jack with a good flashlight and determine the area of leak. Many leaks can be up high and then run down the jack. I've had several leaks on mine up high and fixed with a O ring seal or hose replacement. If it's the main shaft seal down low....unfortunately it has to be replaced with the complete a unit as discussed. They don't service parts separately. HTHs rockin'

P.S. Don't let your fluid reservoir run low (uses Dexron III ATF) then you lose jacks and slide operation altogether.
