Product review (5 stars): WELL WORTH IT-MAKES THE DISHWASHER LIKE NEW AGAIN!
My LG dishwasher was making a lot of noise but still worked okay.  I didn't want to throw it out as it is all stainless inside and out.  I found this part and a YouTube video installation guide online.  It took me a few hours to replace but it wasn't difficult to do.  The dishwasher is like new.
