Have someone locate the area which is making the offending "creak" and apply a proportionate amount of lubrication to the "creak". Depending on the area in which the "creak" is located, thus will determine the appropriate lubricant to be used. Measuring the amount of "creak" to be found after required lubrication, should either alleviate or necessitate future lubrications. Ensure you stow upon your vehicle or mobile canvas accommodation, in a pre-determined position, a portion of the lubricant used. When the "creak" reappears, one will be able to reapply where and when required.
