During Drive Axle Inspection, what should you inspect for leaks and structural integrity?

• A. Axle housing for fluid leaks and integrity
• B. Oil pan gasket
• C. Steering column
• D. Exhaust manifold

Answer: (A)

Focus on the axle housing. This part encloses the differential and holds the gear oil that lubricates the gears. During inspection, look for any signs of fluid leaks around the housing, especially at the differential cover, axle tube seals, and wheel seals. Leaks here point to worn or damaged seals or gaskets and can lead to lubricant loss and gear damage if not addressed. Also check the housing for structural problems: cracks, dents, bends, rust, and loose or missing mounting hardware. Any compromise in the housing or its mounts can affect alignment, integrity under load, and overall driveline safety.

Other items mentioned aren’t part of the drive axle inspection. The oil pan gasket belongs to the engine lubrication system, not the drive axle. The steering column relates to the steering system, and the exhaust manifold is part of the exhaust system.
