Product review (5 stars): DYI in less than 2 hours and save big to fix the noise issues.
My dryer started making loud noises I started spraying a lubricant on where I thought the noise was and that worked for a few weeks but eventually it just stayed loud.  I looked up common fixes and found this kit to replace the moving parts... I did it in about an hour and for the past few weeks it has been quite.  The only item I didn't replace was the belt- the old dryer belt wasn't worn and appeared to be a better product other than that this saved me from spending 350-500 for a new dryer.
