Differential Dropouts and Pinion Supports
The Differential Dropouts and Pinion Supports are key components of your vehicle's transmission system. The differential gears provide the final gear reduction in the transmission and then transmit the reduced engine power to the wheels. The differential's main function is to ensure that all the wheels turn at the right rate when the car rounds a curve. The wheels inside the turning curve will need to rotate at a speed slower than those on the outside of the curve to ensure that all four wheels hug the road while turning. The differential transfers these different speeds to the wheels through the differential case and the planetary gear assembly.

The planetary gear assembly includes the spider gears (planet gear), which are mounted on the differential case's shaft and the side gears (sun gear), which are attached to each half of the axle. The ring gear is driven by the input pinion gear that transmits the driveshaft's motion to it. The differential case, which is attached to the ring gear spins at a speed relative to that of the crown gear. When the vehicle is driving straight, the spider gears do not operate. However, when the vehicle turns, the spider gears begin to rotate causing the wheels to turn at different speeds.
Dropout differential case housings allow you to detach the differential gear-case assembly to work with it. If you experience or notice a drag while driving, it is a possible indication of a defect in the differential gears or dropouts. Other symptoms include a squealing noise while turning or a loud, clunking noise when switching between drive and reverse. Faulty differential gears and dropouts should be replaced at the earliest to prevent your transmission system from sustaining severe damage.
