Hello all,
My wife's 2013 FX37 started leaking fluid from the rear Diff mount bushing.
Our local infinity shop wants 2300 to replace the entire cross member. This includes a full day of labor.
I've read where folks have found the bushing and either did the job them selves, or took the part to a mechanic
So ideally I only need to source the bushing.
Any help here?.

The rear differential bushings on Infiniti vehicles are filled with a viscous fluid that is part of the damping afforded by the rubber bushing. I changed my FX45's to a polyurethane one as the original one was broken (they are notorious for this). Here is a listing of parts -

I had the same issue with the infinity and got a similar quote finally found a guy who fixed it for a lesser price. They rob you for the Infinity logo.
