Product review (5 stars): Excellent replacement, great price!
I needed one assembly to replace a seized roller on a ten year old dryer, I replaced all four so I didn't need to disassemble dryer again in a year. The disassemble of dryer was fairly easy and strait forward but it is a little tricky to remove wire harnesses and you need to look for the locking tabs on connectors. There are videos on YouTube to show you how to disassemble dryer. This part fit perfectly and was a great price compared to $24 at other parts places. It says it is a factory part,but the roller hub is white on replacement and light blue on original, maybe just an updated part. Since the dryer was disassembled  I vacuumed out the dryer enclosure to remove all accumulated dust.
