Dryer was making a loud noise at startup & a constant ticking sound heard most loudly at the exhaust vent outside.

Sounded like something metallic was in the exhaust somewhere bouncing around in the air flow. Upon disassembly, found exhaust clear, but blower fan loose on its shaft. Decided I was hearing the blower slapping back and forth on the shaft. I normally order parts from Sears Direct but recently found your parts to be cheaper. I compared both this time and found your search process and parts list to be more precise. This dryer is 36 years old. Sears only had a generic parts list. PartSelect had the exact model schematic and list. And, the PartSelect price was about 15% cheaper. I ordered the part at 3 PM on a Tuesday (normal ground shipping), and the part was delivered via FedEx at 10 AM the next day, much to my surprise. Getting to the blower requires removing the large face plate that supports the front of the drum, but that is very easy to do and presented no problems with disassembly. Both the startup noise and the clicking are gone. 36 year old machine looks and runs like new again.
