Product review (5 stars): This "kit" worked great to cure the squealing problem my Whirlpool Duet Dryer
This "kit" worked great to cure the squealing problem my Whirlpool Duet Dryer. I watched this video about how to disassemble everything to get to the drum wheels and the idler pulley wheel:  https://www.youtube.com/watch?v=APlWrIcP94g&ab_channel=RepairClinic.com

Took about 1.5 hours start to finish.
