Your vehicle’s drive axles and differential are key components that transfer the engine’s power to the wheels, ensuring smooth and efficient operation. The differential plays a crucial role by splitting power between the right and left wheels and compensating for the speed differences when turning. This keeps your wheels from sliding and ensures stable handling.

Inside the differential are precision parts like the ring and pinion gear, spider gears, and bearings that allow power to be transmitted to the drive axles. Drive axles, depending on their design, may feature universal joints or constant velocity (CV) joints. These components are built to handle the flex and motion of the suspension system as your vehicle drives over bumps, applies power, and makes turns.

Since these are precision-built parts, they require proper lubrication to prevent premature wear and must remain sealed to keep out road grime and water. CV joints are protected by durable rubber or neoprene boots, while universal joints are sealed at each journal. However, these protective components can be torn or damaged over time due to exposure to the elements, leading to issues that require expert attention
