Product review (5 stars): A must have for installing a new washing machine transmission - don't do a rebuild without it
When you decide that the washing machine transmission needs replacement, the best thing to do is order all of the wear parts together with the transmission. The hub nut tends to corrode over time and should be replaced during the rebuild. This was the correct part for my washer. Make sure you have (or purchase) the appropriate wrench for removal and replacement; none of my "normal" shop wrenches fit the nut and I had to wait until the new wrench arrived to complete the job.
