Look for uneven tire wear, strange noises, or a bouncy ride. Maintenance logs should include suspension checks at regular intervals.
Vehicle care plays a big role in avoiding these issues.
7. Cooling System Problems
Risks of Overheating in Fleet Vehicles
Overheating can wreck your engine, lead to warped components, and shut down a vehicle mid-route.
