The drive pulley (DC96-01361A) is an essential component for your Samsung washer, responsible for attaching to the drive belt and rotating the spin basket drive shaft. Symptoms of a failing pulley may include unusual noises during operation, irregular spinning, or a complete halt in the spin cycle. It is crucial to unplug your washer before installation and wear work gloves to protect your hands. Verify your washing machine's model number for compatibility before purchasing.
