Ordered adhesive, Idler arm, spring and belt. Opened up dryer and vaccumed out. Found the fork on idler arm ( where it fits into bushing ) had corrison. cleaned and greased with high temperature grease. Also found screw backing out from rear bulkhead ( upper left ) -tightened. Gave each of the five drum support wheels ( three on rear bulkhead and two on front bulkhead ) a touch of grease. Did not use any of the parts yet,but will keep them. Dryer is working fine now.
