Product review (5 stars): A bit challenging to put in, but totally worth the effort
Our 7 year old LG front load washer started leaking on a Friday night. Thank goodness for the Internet. With one day shipping, this part was at our door by Monday. Trusting the reviews here, stating if you have a front load LG that's leaking, this is the culprit, we ordered this part without even taking the washer apart first.

The install wasn't too complicated, but it took way longer than the 10 minutes some other reviewers and you tubers suggested. The laundry room in our house is pretty tight, so we didn't have the luxury of getting the washer into the optimal position, which would have made it a quicker job. We managed to get by with an adjustable wrench and flat head and Phillips head screwdriver. (Phillips for the back panel, flat to loosen the center - and largest - clamp on the part.)

For handier folks and those who aren't sleep deprived, this may go without saying, but use the drain hose (on our machine it's located on the bottom left behind a little panel) to empty stinky water out before getting started. Also, have a towel handy and use it to prevent scratches to the machine as well as for mopping up. Lastly, since you're already moving the machine away from the wall, it wouldn't hurt to replace the hoses in back, which are supposed to be replaced every five years. We didn't think of this until 10 pm when we were in the thick of things, but I wish we had started prepared to tackle that as well.

Once the new part was in, we tried to find the source of the leak in the old part. We never did. The machine has not had any issues since then, though. It has been handing 1-4 loads a day in our 8 person household with no problem for a couple of weeks now since replacing the part.

Update: Fall-Winter 2016-17. The washer again began gushing water, and I assumed this piece was the culprit. I was disappointed that it had only lasted for two years. As it turns out, the piece was at fault, but because it had come loose during a separate repair to the machine, not because the part itself had failed. We fixed the clamps on both ends and have not had any problems since. If you examine the part and there are no holes, the washer may be leaking because this part isn't attached firmly on either end.
