What problem is the first indication of center support bearing failure?

Excessive chassis vibrations are often the first noticeable problem that indicates center support bearing failure. When the center support bearing begins to fail, it can no longer adequately support the driveshaft. This loss of support leads to an imbalance that causes vibrations to travel through the chassis. These vibrations may be felt more acutely during acceleration or at certain speeds and can be a significant warning sign that something is amiss with the driveshaft assembly.

While other symptoms like squeaking noises, loose steering, and visual damage can occur as the issue progresses, they are typically secondary indicators that arise after the vibrations have started. Thus, recognizing excessive chassis vibrations early on is crucial for identifying and addressing center support bearing failure before it leads to more severe damage or operational issues.
