2005 ChampioN. Why are my seat pedestals rising all by themselves? When I sit on them and pull the lever they go back down then creep up within 10 minutes about 4". Is there any way to disable this and have them down all the time? We are all medium size people and all the way down works just fine. I am thinking about drilling a hole somewhere to relieve the gas charge I know they are worn out. I am not blaming any one. Enrico
