The swing set in this playground is producing an elephant like sound since it has not been lubed since it was installed. This is driving the people who live around the playground crazy. We all hear it. We all hate the noise it makes.
The kids don't care about the noise until someone gets hurt when a bearing breaks and they land face first into the pavement.
WD40 will work for about 48 hours. The playground needs to stop ignoring this safety concern to children who play on this swing set for HOURS a day.
Are they deaf that they can't hear the sound of metal on metal grinding?
