To extend the life of the original ball joints should this be done? Take a spray can of white lithium grease and using the spray straw up under the lip of the dust boots give all four ball joints a shot of grease at each tire rotation. Would this void my warranty? I was planning on doing this with my new 06 liberty when the time comes.
The replacement lower ball joints are the Moog heavy duty greaseable K-3199. What is the Moog replacement number for the upper greaseable ball joints with the upper control arms?
Thank you

Just use a grease gun on the Moogs. Not sure there is a greaseable upper ball joint except for Jeepin Al's. Hmmmm?
