What should you check wheel bearing seals for?

• A. Cracks
• B. Leaks
• C. Wear
• D. Alignment

Answer: (B)

Checking wheel bearing seals for leaks is crucial because the seals are designed to keep lubrication within the wheel bearings and prevent contaminants from entering. If there is a leak, the lubricant can escape, leading to inadequate lubrication of the bearings. Insufficient lubrication can cause increased friction and heat, resulting in premature wear and potential failure of the wheel bearings. Consequently, monitoring for leaks helps maintain the integrity of the wheel assembly and overall vehicle safety. In this context, while inspecting for cracks, wear, and alignment might also be important for general vehicle maintenance, the primary concern regarding wheel bearing seals is ensuring that the lubricant stays contained and that contaminants are kept out, making leaks the most critical issue to check for.
