CV Joint Replacement in Vantaa

When a CV joint needs replacing

The CV joint allows the wheel to steer while transmitting engine power to the wheel. Inside the joint are balls and raceways that slide on the balls and take high torque while turning through different angles. The joint sits inside a protective boot that keeps grease in and dirt out. The first symptom of a fault is almost always a tear in the boot. The boot can be damaged by a kerb or simply split with age, and once torn the grease starts to escape and moisture starts to enter. Caught early, a fresh boot and grease are enough — but if the damage has been ongoing for a few thousand kilometres, the joint itself has already worn and needs replacing. The classic symptom of a worn joint is a clicking or rattling noise heard in sharp corners under acceleration. For example pulling away from a parking space with the steering on full lock produces a "click-click-click" that rapidly gets louder. It's a clear sign the joint needs replacing — leaving it leads to the joint's final failure, after which the wheel can part company with the driveshaft while driving.
