How to Add Front Differential Fluid

The differential is part of the drivetrain in an engine. It transmits power from the engine to the transmission and makes the wheels turn independently so that the wheels can turn at different speeds to let you make turns. Differential fluid lubricates the internal components, including the gears and bearings, of the differential. Pressure, heat, moisture and friction can corrupt the differential fluid and may cause it to evaporate, making it necessary to add front differential fluid. Read on to learn how to add front differential fluid.

Difficulty: Easy

Instructions

1. Locate the front gear differential dipstick on your car's engine. This can be marked in a variety of ways, so check your owner's manual for the exact location.

2. Remove the dipstick to check the level of differential fluid. If the level is low, you will need to add differential fluid.

3. Place a funnel into the dipstick hole. The funnel will help to prevent leaks onto your engine.

4. Pour differential fluid into the funnel slowly. Check the level of differential fluid after every half pint added. To check the level, remove the funnel, replace the dipstick, then pull it out again to check the level.

5. Continue adding differential fluid half pint at a time until the level is satisfactory.

6. Replace the dipstick once the level is satisfactory.

Tips & Warnings

• Check the front differential fluid level every time you change your oil. You should also check the front differential fluid if you notice that your car is not changing gears or turning smoothly.
• If you are constantly getting low readings when you check the front differential fluid, take your car to a mechanic to have it checked for leaks.
