INFINITI Differentials & Parts

Identifying Differential Problems in Your INFINITI

Your vehicle's systems work tirelessly to keep you moving. Regular maintenance is key to ensuring their longevity and efficiency. Differentials allow your drive wheels to rotate at different speeds during turns while transmitting power from the driveshaft. We stock genuine INFINITI differentials and related parts built to handle your vehicle's power output and weight. These assemblies contain precision gears operating in extreme conditions with only a thin film of lubricant for protection.

How Your INFINITI Differential Operates

The differential uses a ring gear, pinion gear, and spider gears to split torque between two wheels while allowing speed differences. When turning, the outside wheel travels farther than the inside wheel, and the differential compensates for this difference automatically. Some INFINITI models feature limited-slip differentials that partially lock the wheels together for better traction. Bearings support the rotating components while seals keep lubricant inside and contaminants out. Your QX60 or QX50 may have multiple differentials if equipped with all-wheel drive, each requiring specific maintenance and care. The gears operate under high loads during acceleration and stress from weight transfer during cornering.

When Differentials Wear Out and Need Service

Differential failures typically begin with worn bearings that create howling or rumbling noises, especially during turns or acceleration. Gear wear produces grinding sounds or vibrations felt through the vehicle floor. Seals leak when rubber deteriorates, allowing lubricant to escape and moisture to enter. You might notice fluid spots under the vehicle or decreased performance on slippery surfaces. Most differentials need fluid changes every 30,000 to 60,000 miles and can last 150,000 miles or more with proper maintenance. Genuine INFINITI differential parts maintain precise gear tooth contact patterns that generic components cannot match, reducing noise and extending service life. The suspension system works alongside the differential to maintain wheel contact and traction.
