Question:
I have a 2021 Grand Design Momentum 320g with the lippert 3.0 leveling system. The front right landing gear appears to be stripped. I couldn’t find a part number on the leg, this is the only number I could find on the leveling system 346005. Just wanted to confirm that the part LC362485 will work for my unit. Thanks

Hey Brett,
The 346005 part number you provided is for the control module which tells me that you have the # LC675817 on your trailer. The Replacement Lead Leg # LC305340 would be a compatible replacement for this system. If the motor and footplate are fine and just the gears inside the leg are shot you can replace just the leg with part # LC362485

Hey Brett, how did things go with the replacement leg for your Lippert 3.0 leveling system? Did the new leg fix the stripped gear issue on your Momentum 320G? Your update could make it easier for others with the same setup.
