The noise may be constant or intermittent. It\u2019s usually loud enough to hear if you don&#8217;t have the radio on.<\/p>\n\n\n\n<p>One common noise that occurs when a u-joint is beginning to fail is a clunking sound. This happens when shifting from forward to reverse or reverse to forward. This means that at least one u-joint is beginning to fail. The good news is that if you replace the u-joint quickly, usually nothing else is damaged.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. Replace Your U-Joints When You Feel Drivetrain Vibration<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"640\" height=\"396\" src=\"https:\/\/gmb.net\/wp-content\/uploads\/2021\/09\/steer-vibration.jpg\" alt=\"Steer vibration\" class=\"wp-image-30135\" srcset=\"https:\/\/gmb.net\/wp-content\/uploads\/2021\/09\/steer-vibration.jpg 640w, https:\/\/gmb.net\/wp-content\/uploads\/2021\/09\/steer-vibration-450x278.jpg 450w, https:\/\/gmb.net\/wp-content\/uploads\/2021\/09\/steer-vibration-600x371.jpg 600w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/figure>\n\n\n\n<p>The most common problem that causes excessive drivetrain vibration is u-joint failure. When a u-joint fails, the driveshaft can start moving outside of its normal rotation. In other words, it becomes too loose. This causes drivetrain vibration that becomes particularly noticeable at higher speeds. You can sometimes feel this vibration through the floorboards and shift lever.<\/p>\n\n\n\n<p>If your truck or SUV suddenly starts vibrating more than usual, check the u-joints ASAP.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Happens When You Don\u2019t Replace Your U-Joints<\/h2>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How Long Will My Vehicle&#039;s U-Joints Last?\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/-cqvgJ3fZOo?feature=oembed&#038;modestbranding=1&#038;rel=0\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Ignoring these symptoms can result in a u-joint that self-destructs.
