Explanation When inspecting a vehicle, you should ensure that the wheel bearing seals are not leaking. Federal and state laws forbid operating an unsafe vehicle.
What are wheel bearing seals?

They can be installed directly into the hub or onto the spindle with dedicated installation tools, dependent upon the seal.
How do you inspect ball roller bearings?
In the case of small non-separable ball bearings, hold the bearing horizontally in one hand, and then rotate the outer ring to confirm that it turns smoothly. Separable bearings such as tapered roller bearings may be checked by individually examining their rolling elements and the outer ring raceway.
How do you check for bearing damage?
Metal-to-metal contact results in excessive bearing temperature. High temperatures result in discoloration of the races and the roller. In mild cases, the discoloration is from the lubricant staining the bearing surfaces. In severe cases, the metal is discolored from high heat.
When replacing a leaking wheel seal what should one pay close attention to?
If one wheel bearing has failed, pay close attention to all of the other hubs on the vehicle, especially if the vehicle has a lot of miles on it.
