Product review (4 stars): Installation not always a breeze
I purchased this kit for a whirlpool washer LSQ8543JQ0 for which this site said this kit was the correct part. It arrived on time, was not defective, and it is indeed the correct part. Not much to review then except for some advice with the installation which can be a b**** (unlike the Mary Poppins DIY videos).

If you look online you can find numerous videos of how to install this part. Its pretty simple, all it requires is a ratchet and an extender! Sure! I first purchased just the dogs from Amazon but I could not separate the upper and lower agitators. I checked some more videos, wondering whether I was doing something wrong or are there differences between models? As per the various DIY videos, I tried standing on the base and pulling. Keep in mind I'm an aging powerlifter and I still deadlift over 400lbs but I couldn't move it a mm. I tried careful hammering of the upper agitator with a rubber mallet. I tried the hot water trick. I tried them all in combination. Nothing worked. Finally I found a comment on another site where someone had used a dremel-type tool to cut away the top of the cam. So I ordered this kit and when it arrived I carefully cut away the fused plastic parts (indicated with red arrows - compare to the point indicated by blue arrow), gave it a small pull and voila it came apart - just like nothing. After that the installation of the new part was easy and all is right in my washing machine world.

I hope this helps someone.
