At first I thought it was the idle pulley making the noise. I ordered it an replaced the pulley. However, the loud squeaking continued. I continued to research the problem, and found that the blower had stripped the spline threads from the metal attachment that goes onto the motor housing shaft. I ordered a new blower wheel. The original blower wheel, in my opinion, had been over tightened at the factory. I am mechanical in mind, do lots of handman work. It took an 18" pipe wrench, with the 7/16" back up wrench to loosen the metal housing that remained after I chised off the plastic wheel housing. I knew the threads were left hand, had to tighten to loosen. I had no issues installing the new blower wheel and put the dryer back together. The dryer works perfectly
