If you're experiencing any abnormal tire wear, steering wander, vibration or shaking, chances are you have some failed ball joints on your rig. Carli truly set the precedent for upgraded ball joints for Heavy Duty Rams upon the release of their lifetime guaranteed ball joints back in 2007, and their new Upper and Lower Ball Joints for the 2003-2013 Ram 2500/3500 are ready to handle everything you throw at them. The ball joint's indestructible nature has proven themselves time and time again when faced with hardcore off-road abuse, oversized tires, or just your average cummins engine with hundreds of thousands of miles. You can try your best to get these ball joints to wear out, but you will fail every single time.
