Description
The OEM Front Propeller Shaft Flex Disc (Part Number: A2104101115)—also known as a flex disk or guibo—is a genuine Mercedes-Benz drivetrain component designed to connect the front propeller shaft to the transmission or differential while absorbing torsional shock and vibration.
Manufactured to Mercedes-Benz factory specifications using high-strength rubber reinforced with fabric or metal inserts, this flex disc reduces drivetrain noise, minimizes vibration, and protects surrounding drivetrain components from sudden torque loads.
A worn or cracked flex disc can cause clunking noises, vibration during acceleration, or drivetrain misalignment. Replacing it with an OEM flex disc restores smooth power transfer, driving comfort, and drivetrain reliability.
