Driveline Service – Usually recommended every 30,000 to 50,000 miles/12,000 to 15,000 miles for some all-wheel and four-wheel drive vehicles (check manufacturer’s recommendation)
Service Includes: Remove and replace old worn-out lubricant from manual transmissions, front and rear differentials, transaxles, and transfer cases. Install gear oil or the additive package required for vehicle application.
Why: Heat, moisture, extreme pressure and loads cause gear oil to break down or to be contaminated, leading to lubrication failure and worn gears. Changing the fluids when scheduled reduces wear and prolongs the life of internal driveline components. All-wheel and four-wheel drive differentials work harder than conventional two wheel drive differentials. For these vehicles, servicing the driveline when scheduled is especially important. With this service, you’ll experience smoother gear shifting, quieter operation and extended component-life, which will reduce major repair costs due to worn gears.
