Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What are the drivetrain specifications for the 2014-Present Infiniti Q70?
What are the drivetrain specifications for the 2014-Present Infiniti Q70?
The 2014-Present Infiniti Q70 offers rear-wheel drive (RWD) and all-wheel drive (AWD) configurations. The AWD system, known as Infiniti's Intelligent All-Wheel Drive, dynamically adjusts torque distribution between the front and rear wheels for optimal traction. The drivetrain is paired with a 3.7L V6, 5.6L V8, or a hybrid powertrain, depending on the model year and trim. Compatibility varies by engine and transmission type, so consult your owner's manual for specific details.
Q2 What maintenance is required for the Infiniti Q70 drivetrain?
What maintenance is required for the Infiniti Q70 drivetrain?
Regular maintenance for the Infiniti Q70 drivetrain includes checking and replacing the transmission fluid every 60,000 miles, inspecting the driveshaft and differential for wear, and ensuring the AWD system's transfer case is functioning properly. Additionally, tire rotation and alignment should be performed every 7,500 miles to maintain even wear and optimal drivetrain performance. Always follow the manufacturer's recommended service intervals.
Q3 How do I replace the drivetrain components on a 2014-Present Infiniti Q70?
How do I replace the drivetrain components on a 2014-Present Infiniti Q70?
Replacing drivetrain components, such as the driveshaft or differential, requires lifting the vehicle and securing it on jack stands. Begin by removing the exhaust system and heat shields to access the driveshaft. Unbolt the driveshaft from the transmission and differential, then carefully lower it. For differential replacement, drain the fluid, unbolt the driveshaft, and remove the mounting bolts. Installation is the reverse of removal. Use a torque wrench to ensure proper bolt tightness.
Q4 What should I do if my Infiniti Q70 drivetrain is making unusual noises?
What should I do if my Infiniti Q70 drivetrain is making unusual noises?
Unusual noises from the drivetrain, such as clunking or whining, may indicate issues with the driveshaft, differential, or AWD system. Start by inspecting the driveshaft for loose or worn U-joints. Check the differential for low fluid levels or metal shavings in the fluid. If the AWD system is malfunctioning, use a diagnostic scanner to check for error codes. Address any issues promptly to prevent further damage.
Q5 How can I optimize the performance of my Infiniti Q70 drivetrain?
How can I optimize the performance of my Infiniti Q70 drivetrain?
To optimize drivetrain performance, ensure regular maintenance, including fluid changes and inspections. Use high-quality synthetic transmission and differential fluids for better lubrication and heat resistance. Upgrade to performance tires for improved traction, especially in AWD models. Avoid aggressive driving to reduce wear on drivetrain components. Consider a professional tune-up to ensure the engine and transmission are operating at peak efficiency.
