When we walk into our front room portion of our rv (05 Holiday Rambler Vacationer) we hear a noise like the jack is coming up a little or the rv is pushing down onto the jacks, kind of like metal sliding thru metal. I am sure its just a body squawk but we have not had it in the past. I checked to make sure we were level and not loosing the jack and its is fine. How does one find a body squawk and is there really a cure for it?
