Can You Still Drive If the Car's CV Joint Is Broken?

[LeCecilia]

You cannot drive if the car's CV joint is broken. The CV joint is located on the car's chassis and serves to connect the driveshaft to the wheels. Essentially, it functions as a universal joint, ensuring continuous power transmission to the wheels regardless of direction (primarily when the wheels bounce). If damaged, power transmission may be interrupted, and even if the car can still move, the steering may become misaligned. Below are additional details: 1. CV Joint Inspection: Check the entire front axle's driveshaft CV joint for any play. Excessive play in the CV joint can cause slight wheel vibration during acceleration. There will also be a noticeable power transfer process when releasing the throttle. You can also manually inspect by firmly gripping the driveshaft and quickly twisting it back and forth to check for any play. New CV joints are typically tight-fitted with almost no noticeable play, at least not detectable by hand. 2. Advantages of CV Joints: The CV joint boot is filled with high-temperature-resistant lubricating grease (molybdenum disulfide), which appears dark blue. Its key feature is maintaining good form and lubrication even under high-temperature conditions, something regular grease cannot achieve.
