Cv Axle Noise Going Straight. When joints wear out, the symptoms will be obvious. It sometimes also occurs when accelerating at slow speed just going straight.faster speeds are fine.
I have had cv's wear out on a couple of cars and they never clicked when going in a straight line. The noise is either coming from the cv axle or the wheel bearing. If an old nut is used, it could work loose and destroy the preload of the bearing.
• a “whirring” noise while decelerating at any or all speeds is most likely caused by bad pinion bearings or loose pinion bearing preload.
Usually the noise gets louder when accelerating in turns. I feel it under the driver's side floor. A bad cv joint will exhibit a clunking noise as the transmission engages. Continuous knocking, while driving at low speeds, may also be due to joint damage.
