washer is shredding clothes

Hi, My washing machine has been snagging clothes and some of them are getting ripped. After washing, at least one item will be wrapped around the agitator a number of times. I thought maybe there was a rough area that might be catching the clothes, but I don’t see or feel anything like that. While I was inspecting it, I did notice that I can pull the agitator up about 1/2 inch off of the agitator base. I’m thinking this gap is what might be snagging the clothes. In searching the internet, I saw something that referenced a spline assembly (between the agitator and the base) that could go bad. Does this sound like the spline assembly needs to be replaced? Or the agitator? I will go check to see if the agitator spins while it is on spin cycle and post an update. Thanks for any help!

Take a look at the video perhaps it is just loose.

Thanks for the reply Denman. I checked it out and it is actually very tight. So tight that I can’t loosen it. I tested it, and the agitator is spinning while a load is washing. I noticed that the agitator does spin freely by hand when the machine is empty and not running. Is that normal? My gut tells me I need to replace the agitator…
