Learn to expertly replace front and rear differential assemblies on your RC off-road vehicle with this step-by-step guide. The video demonstrates front assembly replacement: removing steering linkage screws, chassis bolts, and differential housing screws, followed by inspecting differential gears (spur/pinion) for wear. Key steps include reinstalling universal dogbones, securing the differential with proper torque, aligning front mounts, and reassembling the drivetrain. For the rear assembly, the tutorial covers disassembling the chassis, differential housing, and dogbones, then reinstalling the differential, driveshaft, and rear mounts with precise alignment. Pro tips emphasize gear inspection to prevent drivetrain failure, correct dogbone seating for smooth power transfer, and systematic bolt-tightening sequences to avoid stress points.
