Heat, moisture, extreme pressure and loads cause gear oil to break down or to be contaminated, leading to lubrication failure and worn gears.
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.
