Product review (4 stars): Pair this with a youtube video and save yourself a ton of money.
Our dryer was beginning to squeak terribly every time we ran it. Rather than pay a repairman or buy a new dryer, I found this kit on amazon and looked up an appropriate youtube video and simply followed the instructions. I have no prior history working with appliances and I, despite it taking a couple hours, managed to disassemble my dryer, install the new components and re-assemble the unit. The kit comes with pictograph instructions that were very helpful and the dryer now is very quiet.
