Product review (5 stars): Saved me lots of $$$!
Perfect! Five minutes to install and the washing machine works as new. LG made a cheap original part. The spline rounded out and the agitator did not work. I almost bought another washing machine until I read the reviews here to help explain the issue. I have attached a picture of the rounded out old part and a picture of the new part so you might understand the issue. The spline is on the under side of the Washplate that attaches to the shaft.
