The tub in my washing machine was hitting the sides of the enclosure making a terrible noise.  I replaced the existing suspension rods with these and the problem is resolved.  The interesting part is that there was no discernible difference between what I took out and these so it must have something to do with subtle changes in the springs or other parts over time.
