What should wheel bearing seals be checked for?

Wheel bearing seals play a crucial role in the overall integrity and performance of the vehicle's wheel assembly. Checking for leaks is vital because the seals are designed to keep lubricating grease or oil in the bearing and prevent contaminants like dirt and water from entering. When seals leak, it can lead to inadequate lubrication of the bearing, which increases the risk of overheating and premature wear or failure of the bearing itself. By ensuring that the seals are intact and not leaking, you help maintain the proper function and longevity of the wheel bearings.

While cracks, rust, and wear and tear are important factors to consider during regular maintenance, the primary role of the wheel bearing seals is to prevent leakage. Therefore, regular checks for leaks should be emphasized to ensure proper sealing and lubrication.
