1985 GMC S15 Drivetrain Service

Your S15 drivetrain transfers power from your engine to the wheels. It spans the length of your vehicle, from the transmission to the axles. It’s one of your S15’s most complex systems and includes everything after the engine transmission: driveshafts, axles, joints, differentials, and wheels. When you maintain the drivetrain in your 1985 GMC S15, you help maintain your vehicle's power. You can minimize repairs by following GMC's recommendations for checking and changing differential fluids, and lubricating bearings and gears.

When to Get GMC S15 Drivetrain Repairs

You want to come see the technicians at Firestone Complete Auto Care. We can take care of most 1985 GMC S15 drivetrain components including the driveshaft, CV axles, and CV joints. Your S15 might need driveshaft repair if you notice heavy vibrations in your floorboards, clunks when shifting, resistance when turning, or vibration as your vehicle accelerates.
