What Does the Drivetrain Do In Your 1985 BMW 735i

Your 735i’s drivetrain has a very important job. It transmits power from the engine to the wheels. It spans the length of your vehicle, from the transmission to the axles. It's one of the most complex systems in your 735i and is made up of everything after the engine transmission: axles, wheels, driveshafts, differentials, and joints. When you maintain the drivetrain in your 1985 BMW 735i, you help maintain your vehicle's power. Follow BMW's recommendations for lubricating bearings/gears and checking/changing differential fluids to minimize repairs over time.

When to Get BMW 735i Drivetrain Repairs
