FWD driveshaft problems are usually indicated by ________.

Issues with front-wheel drive (FWD) driveshafts often become apparent through the presence of grease emanating from a torn boot. The driveshaft, specifically the constant velocity (CV) joint, is protected by a rubber or plastic boot that contains lubricant. If this boot tears, the protective seal is compromised, causing the grease to escape and potentially leading to CV joint failure if not addressed. This leakage is a clear visual indication of a problem, allowing for early diagnostics and preventative maintenance to avoid more severe issues in the drivetrain. Recognizing this symptom can help in taking the necessary steps to repair or replace parts before they lead to greater mechanical failures.
