Final drives transfer power from the transmission to the wheels, typically housing the differential and associated gears. These robust assemblies are located on the axle, directly driving the wheels via constant-velocity joints or side gears. Internal gear ratios within the final drive provide a further reduction in speed and corresponding increase in torque. Components include hypoid or helical gears, differential carriers, and reinforced housings designed to withstand high loads. Final drive assemblies are critical for overall vehicle performance and require precise lubrication and maintenance to prevent failure.
