Rebuild Kit: Rear Adjustable Control Arm (03+ 4Runner/FJ/GX, Uppers)
Those Johnny Joints are tough, but (like almost everything else on an off-road vehicle) they are a "wear item" and won't last forever. But, one of the great things about Johnny Joints is that they are serviceable! Maintenance is key! Get yourself some rebuild kits and a tube of fresh grease, along with an assembly tool while you're at it. Complete new joints are available as well.
Compatibility: 4th and 5th Gen (03+) 4Runner, FJ Cruiser, GX470, and GX460 UPPER arm only. If you are rebuilding one of our other rear arm kits, use the specific pages in this collection. Thank you!
Note: Opt Offroad Rear Adjustable Upper Control Arms are equipped with narrow body joints on both end. Rebuild kits will include the necessary components to rebuild/replace all four joints accordingly. If you want to rebuild/replace less than all four joints, please contact us and we will help you directly!

Johnny Joint Grease Information:
RockJock's premium quality, long lasting grease has be proven in all of our own competition and recreational vehicles over the last 15+ years. Non-moly greases eventually dry up and cause squeaking, friction and component wear. We only use and recommend moly grease for maximum longevity and smooth quiet operation of components.
RockJock® grease is a high-moly based petroleum lubrication that is specially formulated to reduce friction and increase performance while extending the life of your Johnny Joint® Rod Ends. Includes one 14oz tube of grease, fits in a standard grease gun.
