thank you everyone for your help. I found a utube video by AlexDoesDIY where he showed how to strip the unit down and once I knew that it was easy.
It turned out that these drums are a little out of concentric so the Drum was rubbing against the back of the fan I moved it towards the grill 1/4" there was actually a fair amount of room and it works fine. The other Utube video was useless it suggested they could fix everything on a dryer it was car crushing yard.
Thankful or Grateful Peter
