Who is correct regarding the reuse of wheel bearing grease seals?

Counterman A is correct because typically, wheel bearing grease seals are not designed to be reused. These seals are crucial for maintaining the integrity of the bearing assembly by preventing grease from leaking out and contaminants from entering. When a seal is removed, it can often become damaged or lose its effectiveness due to deformation or wear.

Using a new seal ensures that the bearing is adequately protected and can function properly, reducing the risk of premature failure. While it might seem feasible to reuse seals if they appear undamaged, doing so could compromise the reliability of the entire wheel bearing setup. Therefore, the emphasis on replacing seals reinforces best practices in automotive maintenance, ensuring the longevity and safety of the components involved.
