The factory rear differential bushing on the 370Z and G37 is a well-known weak point, often failing over time and leaking fluid. This 370Z came in for preventative maintenance, so we installed a Z1 Motorsports Rear Differential Bushing kit.
Upgrading to a solid or polyurethane bushing improves drivetrain response, reduces wheel hop, and ensures power is transferred more efficiently to the ground. While we were in there, we also changed the differential fluid—something many owners overlook but is crucial for maintaining smooth operation and longevity.
If your 370Z/G37 has clunking noises or excessive drivetrain movement, it might be time for this upgrade!
