Process/Skill Questions:
- Why might an obstructed breather vent be the cause if oil is leaking from a wheel seal?
- When an oil seal was replaced but there were no signs that anything was wrong with the seal, why should the breather be removed and cleaned?
- Why should the breather be removed and cleaned more often for vehicles operating in road construction settings?
