As a CV joint loses lubrication, the moving metal parts wear on one another and slowly degrade over time. Noises, vibrations, and loss of acceleration through turns are all signs that a CV joint may require a replacement. Another problem that might lead to a CV joint replacement is your CV boot. The CV boot encases the CV joint to retain the necessary amount of grease to keep the joint lubricated. If the grease leaks, the CV joint will lose the proper amount of lubrication necessary to keep the internal CV joint parts from excessive wear.
If you experience the symptoms of a worn or damaged CV joint and the joint is not promptly replaced, the minor issue will cause additional damage to your vehicle and lead more expensive repairs in the future. The cost of replacing your CV joint is cheaper than the major repairs you may face if a faulty CV joint is left untreated.
