Product review (5 stars): No more screeching
Our ($2600) LG Tromm washer and dryer are 12 years old and both were starting to make loud noises, so I assumed it was time to replace. The dryer started to screech and clunk so I assumed it needed a belt.  It turned out that the old belt was perfect and all the issues were coming from these roller wheels.  The 2 (of 4) wheels that support the most weight had seized and so the dryer wore flat spots on the rubber wheels that just kept getting louder.  I was shocked the drum would even turn with half the wheels stuck but now it runs like brand new again.  The repair looks much worse than it actually is because you remove the top and front of the dryer, but this stuff is built to be serviced so don't be discouraged.  All I used was a screw driver and needle-nose pliers.

 the last six weeks I've repaired our washer, dryer, dishwasher, pool motor and pool heater.  I spent LOTS of time researching and learning but I saved about $2500 in repairs and now I know a lot more about how it all works.
