2023 BMW 740i Drivetrain Service

Your 740i’s drivetrain has a very important job. It transmits power from the engine to the wheels. It spans the full length of your BMW, from back to front. It’s one of your 740i’s most complex systems and includes everything after the engine transmission: differentials, driveshafts, joints, axles, and wheels. When you maintain the drivetrain in your 2023 BMW 740i, you help maintain your vehicle's power. You can minimize repairs by following BMW's recommendations for checking and changing differential fluids, and lubricating bearings and gears.

When to Get BMW 740i Drivetrain Repairs

We can fix many 2023 BMW 740i drivetrain components including the CV joints, CV axles, and driveshaft. Your 740i might need driveshaft repair if you notice heavy vibrations in your floorboards, clunks when shifting, resistance when turning, or vibration as your vehicle accelerates.
