Terra Firma Automotive supplies genuine Nissan transmission bearings that keep your Z32 manual gearbox operating smoothly and quietly at highway speeds. This overdrive gear bearing is the exact OEM needle bearing that supports the 5th gear (overdrive) on the main shaft. Precision-engineered to Nissan’s specifications, it provides the necessary radial support and low-friction rotation required for reliable high-gear performance under sustained load and high RPM.
Overdrive bearings in Z32 transmissions often develop noise, vibration, or play after high mileage due to constant high-speed operation. This authentic replacement restores smooth, silent rotation of the 5th gear, eliminates whining or humming in overdrive, and reduces stress on the gear teeth and synchro components. Its factory-correct dimensions and tolerances ensure perfect fitment and proper end play during reassembly.
At Terra Firma Automotive we focus on these specific high-wear bearings that are critical for a quiet and durable transmission rebuild. Whether you are addressing gear noise on a long-distance twin-turbo, refreshing the overdrive assembly on a naturally aspirated model, or performing a complete transmission overhaul on your 1989–1996 Fairlady Z or 1990–1996 300ZX, this overdrive gear bearing returns the gearbox to factory-smooth operation in top gear.
