The Fabco 309-40-2 or 309402 is a top shaft. Shafts of this kind carry driveline power on bearings inside a sealed housing that is filled with fluid to lubricate and cool them, so the shaft and its bearings turn every time the unit is under power.
When one is tired it tends to show itself with grinding or clunking, a whine that climbs with throttle, vibration, or dark, metal-flecked fluid. Those are good reasons to inspect the shaft and bearings together before a small problem becomes a teardown. A genuine Fabco part from Pro Gear and Transmission. Call us with your unit details to confirm proper fit.
