Product review (5 stars): Good for another several years! Not easy to install, but it can be done!
I installed this today - our LG washer is at least six years old and the gasket had not been replaced. It developed a small tear and I figured it was time. Like many others here, I used a YouTube video as a guide - it was very good, but it seemed my older model was slightly different in that the control panel was secured with five, not four screws on front (easy to see) and one in the back (not).

The gasket secures to the drum housing with one spring clamp and the front panel with another. Each time you have to make sure the gasket is seated properly on the rim - for the drum housing I found that a bit of diluted soap on the gasket made it much easier to snap into place. The clamps are a pain, but I managed to get them on without the overpriced LG tool, using ViseGrips as suggested in the video, Even so it was frustrating as the gasket would tend to pull off the rim when I tried pulling on the clamp. I did get it in the end.

I was mortified to see that the drain tube for the old gasket was completely clogged with gunk. I will take more care to keep that clean in the future.
