I changed out the gear oil in the front diff on the Burb on Saturday night to Sunday morning (pump broke Saturday night, couldn't replace until Sunday morning). It came with a conventional gear oil in the front and the appropriate fill level, per the OM, is to the bottom of the fill hole. The rear diff came with synthetic fluid and the appropriate fill level is 5/8 to 1 5/8 inch below the fill hole. However, my Haynes manual does not distinguish between the front and rear diffs in the "Differential lubricant change" section and simply states in the final step:
Quote:
Use a hand pump, syringe or squeeze bottle to fill the differential housing with the specified lubricant until it's level with the bottom of the fill-plug hole. If using synthetic axle lubricant, the level should be below the fill-plug opening by 5/8-inch to 1 5/8-inch on 1500 Series models, but no more than 3/8-inch lower than the hole on 2500 Series models."
I have a 1500 Series and filled it to the bottom of the fill hole. Should I extract some of the fluid from the front diff to bring it to 5/8 inch below the fill plug hole?
