Golf Cart Squeaking
 

We have 2007 Yamaha gas golf cart. Making a terrible squeaking noise that is coming from where driver’s side rear metal support meets the roof. It squeaks even when it’s not running, as soon as my husband sits down in driver’s seat. He removed all of the bolts, lubed inside the support and bolted it back up again but that didn’t work. Any suggestions what this could be? Any help is appreciated.
