Can Buick drivetrain maintenance help me save money?

Yes. Servicing the drivetrain system can help you avoid more significant repairs. A bad drivetrain can put more stress on other vehicle components.

How do I know if my Buick drivetrain is damaged?

Noises toward the back of your Buick LeSabre, leaking fluid, trouble turning — these could all be signs of drivetrain damage you want to address. Take action before something more severe happens.

How often should I come in for Buick LeSabre differential service?

Double check your owner’s manual and talk with a technician. Differential service frequency varies from car to car. At a minimum, we recommend getting your differential inspected and the differential fluid changed as a part of your regular vehicle maintenance routine since your vehicle cannot function without a differential.

What triggers the malfunction indicator light (MIL) in a LeSabre?

The malfunction indicator light — also known as the check engine light — on your LeSabre can illuminate for a variety of reasons, including engine issues, electrical problems, damaged sensors, transmission problems, misfires, and faulty connections.

Is it possible to reset the LeSabre malfunction warning light on my own?

Resetting a malfunction warning light at home may be possible sometimes, but it is never recommended. The check engine light is commonly triggered by a misfire, fault or malfunction in one of the vehicle's systems. It is important to identify and fix the underlying problem to ensure the safety and reliability of the vehicle. Resetting the check engine light without addressing the underlying issue may temporarily remove the warning, but it will not fix the root cause of the problem.

How serious is a drivetrain malfunction in my LeSabre?

If your LeSabre has a drivetrain malfunction, don't wait. Get it checked out by a professional mechanic. Identifying the underlying cause and performing the appropriate repairs right away can help prevent further damage and avoid unsafe driving conditions.

Is the transmission considered part of the drivetrain in my LeSabre?

Yes, the transmission is an essential part of your LeSabre’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your LeSabre forward. Other components in the driver train include the axles, differential, and driveshaft.

All About 1986 Buick LeSabre Drivetrain Service

Your LeSabre’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 a very intricate system of moving parts and is comprised of everything after the engine transmission: axles, wheels, driveshafts, differentials, and joints. When you maintain the drivetrain in your 1986 Buick LeSabre, you help maintain your vehicle's power. You can help prevent repairs by checking and changing differential fluids, and lubricating bearings and gears according to Buick's recommendations.
