Dryer tears holes and get stuck in side of dryer.What part do I need to fix it,and how do I fix it

The likely part you need is a front bearing with glides. Unplug the dryer and pop the top up. Remove the screws holding the sides to the front. Disconnect the door switch wires and remove the front. Across the top of the drum is a strip of felt that used to have 2 plastic glides on it which are now by your toes. Remove the felt (peel it off) and replace with a new one.
