These washers with bonded rubber insulators can look pretty ugly by now.

I found an update repair option a few years back on 99 Impreza front suspension. Lower control arm, rear bushing location. Just the rubber, figuring we can glue to original washer. Probably about 4 mm larger diameter that gets swallowed up pretty easily. The first pic is actually original unit overlaid on the Impreza insulator, you might just imagine you can see this  looks like a shadow

They look to be a better quality or more robust rubber ring.

Thought worth sharing with pictures here. If it went to Facebook it likely just be seen, forgotten, never to be found again

I used an old conveyer belt. It was a bit tight but it works well. Everything is solid, no real new noises either. 

Gen3 Liberty and Outback’s could be another source on the rear end. I’ll check it out next time I’m close to Basil (Sister’s Gen3 RX).
