How do you know when front 4X4 joints bad?

You can tell if the front 4x4 joints are bad by looking for signs such as unusual noises like clunking or popping when turning, vibrations felt through the steering wheel, or difficulty in engaging the 4x4 system. Additionally, visual inspection may reveal grease leaks or worn-out boots. If the vehicle exhibits poor handling or a noticeable increase in play in the steering, it’s also a strong indicator that the joints may need attention. Regular maintenance checks can help catch these issues early.
