How to Determine and Handle a Faulty Outer CV Joint
3 Answers
Typically, there will be a regular "clicking" sound during turns or bumps, and in severe cases, loss of power may occur. If there is a "clicking" sound during turns, it is usually due to a faulty outer CV joint. If the "clicking" sound occurs during bumps, this indicates a faulty inner CV joint. The CV joint tends to make a "clicking" sound only when the car accelerates, rarely during coasting. Simply replacing the CV joint will resolve the issue.
To determine if the outer CV joint is damaged, I usually pay attention to abnormal symptoms while driving. A noticeable clicking sound when turning, especially during sharp turns or at full lock, is a strong indicator of an outer CV joint issue. Significant wheel vibration during acceleration, causing the car to feel shaky, should also raise concerns. A visual inspection is straightforward: crouch down and check for grease leakage near the tires or signs of damage/wear on the CV boot. If damage is confirmed, don’t hesitate—replace the CV joint assembly immediately. I’ve tried DIY replacement, but the process is cumbersome, requires specialized tools, and risks improper installation leading to new problems, so I trust professional repair shops more. During routine maintenance, have a technician inspect the CV joint condition to avoid sudden failures. Ignoring a damaged CV joint compromises steering safety and increases the risk of losing control during turns. Early detection and repair save money and ensure peace of mind. Developing a habit of listening for unusual sounds after driving is key to prevention.
From a DIY enthusiast's perspective, I'll share how to identify a faulty CV joint. The main methods are listening for sounds and hands-on inspection. If you hear clicking noises accompanied by slight vibrations when turning or accelerating, there's a high chance the outer CV joint is damaged. For more accurate diagnosis, lift the car in a garage and rotate the wheels to listen for abnormal sounds. Visually check for grease leakage or torn boot seals around the CV joint. For replacement, prepare to remove the wheel and driveshaft assembly, then install a new CV joint with fresh grease and seals. I recommend using reliable parts brands like OEM, but unless you're experienced with proper tools, don't force it - improper handling may cause more wear and waste time. Timely replacement prevents vehicle loss of control or driveshaft breakage. Personally, I perform monthly undercarriage checks which effectively reduces major repair needs.
