I ordered the tension/idler arm assembly, 4 drum support wheels and 4 clips. I then watched the video on how to replace the items I ordered. It took me about 3.5 hours, longer than what the video said as it was a first time experience and the dryer in the video was not the exact model as mine. I did find out that I didn't need the extra clips as they came with the wheels, an extra $20.00 I didn't need to spend. That's the reason for 4 stars instead of 5.
