Front Right Wiper Arm - 1990 300ZX Z32

The Nissan 300ZX Z32 platform utilizes distinct left and right wiper arms with mirror-image curvature that are not interchangeable. For the front right position, Genuine Nissan part number 28886-40P00 was specified across all 1990-1996 USDM production, including both VG30DE and VG30DETT variants. The companion driver-side arm is 28885-40P00. When inspecting junkyard donors, check for spring retention clip fatigue and splined bore wear—common failures after three decades of cyclical loading. Before removing the 14mm tapered nut, scribe the windshield glass to mark the park position; the Z32 spline interface is prone to seizing and improper alignment causes blade-to-hood contact. While 1989-2000 JDM Fairlady Z models share casting marks like 40P00, remember that right-side designation reverses for RHD vehicles. Always verify the wiper transmission linkage hasn't been modified with aftermarket geometry changers that alter arm sweep angles.
