I used the video link provided in the website, followed the process step by step. it was rally hard to take out the old blower wheel (was jammed as it was really old). I had to broke the wheel and used saw to cut it off. After that, it was a quick re-assemble the dryer. Now it is working perfectly. Instead of spending at least US$ 600 for a new dryer, I spent about US$ 30 for parts and shipping and spent about 2 hours for fixing it.
