Wife has a Volvo V70XC, which is perhaps the worlds squishiest car. Everything is hung is huge soft rubber bushings.
While looking at replacement bushings, I came across this odd bushing. Then I read IPDUSA's description. Priceless!
Product Description
Truth be told, we don't know exactly why Volvo calls for these on P2 models. The cars didn't originally come with them.
Plastic washer is installed between subframe bushing and steel washer.
