I'm trying to identify this leaking seal in the rear crossmember on my G37S. I have service manuals in pdf format, but that particular computer is currently inoperable. Could anyone help ID this for me?

 

That's the bushing for the rear diff where it mounts to the cross member. This was a common problem on the Nissan 350Z; I guess it may be an issue on the G's too.

 

Thanks tejas, a google search confirmed that it was apparently very common. Amazingly, it sounds like Nissan's solution is to replace the entire crossmember. Thank goodness for 7 years of warranty coverage. How stupid is replacing a massive piece of hardware when all you need is a solid bushing.

 

Yeah, kind of stupid that it was designed that way...I had a Z, but fortunately, I never had that problem.
