FLUID RECOMMENDATION AND LEVEL CHECK
It is recommended that the rear axle lubricant level be checked at each engine oil change interval. The proper lubricant is SAE 80 or 90 GL-5 gear lubricant. The filler plug is removed with a 3 / 8 " drive ratchet and short extension. When the unit is cold, the level should be 1 / 2 " below the filler plug hole; when it is hot, it should be even with the hole. Lubricant may be added by a suction gun.
