Does the abnormal noise from the Nissan Qashqai's universal joint cross shaft affect driving?

Nissan Qashqai's universal joint cross shaft abnormal noise does affect driving. Here is the relevant introduction about universal joints: 1. A universal joint, also known as a universal coupling, is a mechanical component that enables power transmission at varying angles. 2. It is used in positions where the direction of the transmission axis needs to be changed, serving as the "joint" component of the universal transmission device in the vehicle's drive system. The classification of universal joints is expanded as follows: 1. Non-constant velocity universal joint: When the angle between the two shafts connected by the universal joint is greater than zero, the joint transmits motion with a varying instantaneous angular velocity ratio between the output and input shafts, but with equal average angular velocity. 2. Quasi-constant velocity universal joint: Refers to a universal joint that transmits motion with equal instantaneous angular velocity at the designed angle and with approximately equal instantaneous angular velocity at other angles. 3. Constant velocity universal joint: A universal joint that transmits motion with always equal instantaneous angular velocity between the connected output and input shafts. 4. Flexible universal joint: A universal joint that has significant elasticity in the torsional direction.
