i also replaced the top drum glides. After i finished and turned the dryer on it sounded like a rubbing sound. Is that Normal?
More like a sciffing or light scratching sound is normal....since we cannot hear your dryer we cannot really say what is happening or not happening.
This might help as well....
The super film strength, long lasting, clear lubricating compound ( great for dryer rear drum bearings and some dryer front glides ).
