What should wheel bearing seals be primarily inspected for?

• A. Cracks and rust
• B. Leaks
• C. Loose fittings
• D. Corrosion

Answer: (B)

The primary purpose of inspecting wheel bearing seals is to check for leaks. Wheel bearing seals play a crucial role in keeping the lubrication contained within the wheel bearings while preventing dirt, water, and other contaminants from entering. If a seal is compromised and leaking, it can lead to a loss of lubricant, which is essential for the smooth operation of the bearings. Insufficient lubrication can cause increased wear, overheating, and ultimately, bearing failure. While other issues such as cracks, rust, loose fittings, and corrosion are also important to monitor, the most immediate concern associated with wheel bearing seals specifically is ensuring that they are functioning properly to contain lubricant and block contaminants, making leak detection the priority. This focus on leaks helps maintain the integrity and longevity of the wheel bearing system.
