RWD

📖 YOUCANIC Automotive Glossary

RWD (Rear-Wheel Drive) transmits engine power through a driveshaft to the rear differential, which distributes torque to the rear wheels via axle shafts. RWD provides balanced weight distribution (especially with front-engine layout), better handling dynamics, higher towing capacity, and separates steering from driving forces for more precise control. RWD is standard on trucks, performance cars, and luxury vehicles.

RWD-specific components requiring diagnosis include the driveshaft (U-joint wear causes vibration), rear differential (gear noise, fluid leaks), differential bearings, and rear axle seals. The YOUCANIC UCAN-II can read differential control module codes on vehicles with electronic limited-slip differentials (eLSD).
