Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What are the drivetrain specifications for the 2009-2013 Infiniti G37?
What are the drivetrain specifications for the 2009-2013 Infiniti G37?
The 2009-2013 Infiniti G37 features a rear-wheel-drive (RWD) or all-wheel-drive (AWD) system, depending on the model. The AWD version uses Infiniti's ATTESA E-TS system, which automatically distributes torque between the front and rear axles for optimal traction. The drivetrain is paired with a 3.7L V6 engine producing 330 hp and 270 lb-ft of torque, mated to either a 7-speed automatic transmission or a 6-speed manual for the coupe models.
Q2 What maintenance is required for the G37 drivetrain?
What maintenance is required for the G37 drivetrain?
Regular maintenance for the G37 drivetrain includes checking and replacing the differential fluid every 30,000-50,000 miles, inspecting the driveshaft and CV joints for wear, and ensuring proper alignment. The AWD system requires periodic checks of the transfer case fluid. Transmission fluid should be replaced every 60,000 miles, and the clutch system (for manual models) should be inspected for wear and proper operation.
Q3 How do I replace the driveshaft on a 2009-2013 Infiniti G37?
How do I replace the driveshaft on a 2009-2013 Infiniti G37?
To replace the driveshaft, first, secure the vehicle on a lift or jack stands. Remove the exhaust system and heat shields for access. Unbolt the driveshaft from the differential and transmission. Mark the driveshaft orientation for proper reinstallation. Install the new driveshaft, ensuring it is aligned correctly, and torque the bolts to the manufacturer's specifications. Reinstall the exhaust system and test drive the vehicle to ensure smooth operation.
Q4 What should I do if my G37 drivetrain makes unusual noises?
What should I do if my G37 drivetrain makes unusual noises?
Unusual noises from the drivetrain may indicate worn components. For clunking sounds, inspect the driveshaft U-joints and CV joints. Whining noises could point to differential or transmission issues, requiring fluid checks or component replacement. Vibrations may indicate an unbalanced driveshaft or worn mounts. Diagnose the issue by inspecting these components and consult a professional mechanic if necessary.
Q5 How can I optimize the performance of my G37 drivetrain?
How can I optimize the performance of my G37 drivetrain?
To optimize drivetrain performance, use high-quality synthetic fluids for the differential and transmission. Regularly inspect and replace worn components like bushings and mounts. For AWD models, ensure the ATTESA E-TS system is functioning correctly. Upgrading to performance driveshafts or lightweight components can reduce rotational mass, improving acceleration and responsiveness.
