Specifications

The TDA2234F604 Side Gear from CCC Parts is a direct aftermarket interchange for Meritor 2234F604, used inside Meritor/Rockwell SSHD differentials. Side gears sit at the ends of the carrier, spline to the axle shafts, and mesh with spider gears to allow wheel-speed differentiation in turns. This gear is manufactured from heat-treated steel for high surface hardness and fatigue resistance, and its 16-tooth, 20-spline configuration maintains correct contact and load distribution. Replacing a worn side gear helps reduce noise, restore backlash control, and protect the entire differential assembly during heavy-torque service. Sold by Wofford Truck Parts.
