Where to aquire rubber bushings?
Generally speaking, appliance repair parts are most easily found at an (these days, mostly online) appliance repair parts specialist dealer, as they are not generally &quot;standard&quot; parts (or if they were, you already found those ones by other means.)
Another option (if you just can't find one) is to make your own replacement part using something like silicone rubber that you can form yourself and let cure.
