Product review (3 stars): The top end that attaches to the washer drum is ...
The top end that attaches to the washer drum is too small for my WF210AN washing machine IF the bushing is left in.  I had to use a long machine screw and deep socket to pull the bushing out, leaving the 5/8" ID rubber grommet in place as the same size as the mounting stud required.  Most people won't have the hardware or ability to pull a bushing, but anyone can tap one in with a hammer.  The kit should come with the bushing loose for installation only when required by the washer model.
