BEARING-COUNTER GEAR

Countershaft Gear Bearing for Nissan/Infiniti ⚙️

Keep your transmission quiet, cool, and precise with this OEM-grade counter gear support bearing. It stabilizes the countershaft in rear-drive gearboxes, holding gear mesh on-spec for smooth, confident shifts .

Why this part is needed ✅

It carries radial and axial loads from the counter gear, reduces friction, and preserves oil film. A fresh bearing restores alignment, cuts drivetrain whine, protects synchros, and extends gearbox life.

How it works

Hardened steel rollers run in a precision race, guided by a cage for even spacing. With proper clearance and lubrication, the bearing supports the counter gear at high RPM, keeping backlash correct and heat under control ️.

What happens if it fails ❗

Expect growl under load, speed-based whine, metal glitter in fluid, hot smell, notchy shifts, or pop-out. Ignoring it can seize rollers, pit gear teeth, crack the case, and force a full rebuild. Replace at first signs, especially after clutch work or hard launches .
