Dry has heat but clothes not drying

[LEFT][COLOR=#000000]My dryer dried a load and then suddenly starting making a noise when i filled it again turned it on after 40 mins which is ample time for my clothes to dry they were not dry.. heated and tumbling but no air from the outside vent . no apparent clogs from the outside . other than checking for kinks on the inside hose my concern is the noise almost like bearings going out but the not the complete grinding metal to metal sound ..any suggestions?

I would remove the blower housing and check it for lint build up.
Here is a link with photos that show what I’m talking about.
Why does my dryer take so long to dry a load of clothes?
