Do-It-Yourself Stories from Customers like You Worn out bearings   Linda B. • San Diego , CA • November 23, 2015

After watching the video carefully and taking notes for step-by-step dismantling of the LG washer, I took it apart methodically placing each item on a table in the order removed. I was able to remove and replace the bearings with no problems following the tips and tricks. The spider did not seem to be in bad shape but since I had a new one, it seemed reasonable to replace it as well, but it was difficult to extract the old one from the drum. The bolts are assembled with weld glue, so it is a... Read more

Do-It-Yourself Stories from Customers like You Loud noise during spin cycle   Steven S. • Celina , OH • March 10, 2019

I started by watching the video and it was very helpful. I would make one suggestion. On our model the weights on the tub sit very close to the front gasket. It is much easier to put the gasket on the tub before you put the weights on. Also, since the washer was tore apart, I replaced the hoses and seals and shocks since the machine is about 8 years old. The shocks made a huge difference. It spins like it did when it was new. Thanks for the video, it was very helpful. Read more
