Squeaky Dryer

[snapper88]

I have a squeaky dryer and I was going to order the following 5 parts to replace them in my dryer: Rear Drum Bearing Kit; Front Felt Glide Assembly (drum glide); Seal-Basket Lower; Idler Pulley Assembly; and Dryer Belt. I believe it is probably the 1st and 2nd item listed above that is the root cause of my dryer squeaking but while I was fixing those I thought it might be a good idea to replace some other parts for maintenance while I have the dryer apart. Is there any other maintenance type parts I should buy? Meaning is this list comprehensive enough? Is it too much. I would appreciate your advice. Also how can I get some instructions to replace the 5 listed items. Thanks in advance- Marilyn
