From what it looks like, the Lippert Venture Lead Leg Repair Kit for 5th Wheel RV Landing Gear # LC146059 would work on your landing gear, but without knowing the brand and capacity it's tough to confirm this. If you can find any identifying marks on the legs I can confirm this kit will work for you; it's designed for Venture landing gear legs, but I do know there are others this would work on. view full answer...
