What should you check the wheel bearing seals for?

Checking the wheel bearing seals for leaks is crucial for maintaining the integrity and performance of the vehicle’s braking and wheel systems. The seals are designed to keep lubricant in and contaminants out of the bearings, which are essential for their function. If there are leaks, it indicates that the lubricant may be escaping, leading to inadequate lubrication of the bearings. This can cause increased friction, overheating, and eventually, bearing failure. Identifying leaks early can help prevent more serious mechanical issues down the road, ensuring the safety and reliability of the vehicle.

While wear and tear, noise levels, and temperature are important factors to consider when inspecting wheel bearings, the presence of leaks in the seals directly signifies a failure in their ability to protect the bearings, making it a critical area to inspect regularly.
