I fixed my similar symptoms with just the RH mount, but research did show the dog-bone (bottom or rear mount) to also be an issue. Also had found a few reports of issues with new RH mounts. Pull off cover of mount and feel the top of the rubber bellow. I believe that it should still be firm.
I coupled my RH mount with a timing belt change, and plan on the dog-bone next month with changing the struts. I have the steering wheel shimmy and can bounce the front left fender.
