Ah yes....The "front transverse link". I do believe those bushings have liquid silicone in em, because I sat a jack stand under it and missed the "front suspension member" and the stand edge went right between the "front suspension member" and the transverse link, pinching that bushing and causing it to leak. Odd that those two Zs pictured have em leaking too...wonder if they're just sh!++y bushings?
I believe Spoon also said they're liquid filled. I asked him in PM and he never replied.
Anyway, SPL makes FKS front impact bushings that replace 'em.
