The 4×4 system includes differentials and sometimes a transfer case, which all generate power to the wheels. The differential works with your transmission to deliver power from the engine to the axle that turns your wheels. Using a series of gears, the differential allows the wheels to turn at different speeds (the outside wheels need to turn faster than the inside wheels during a turn), enabling corner turning with improved traction.
High operating temperatures can cause the differential fluid to break down. When this happens, the gears won’t work together smoothly. If the differential gears start to grind together, continued driving can cause expensive damage. Replacing the old contaminated fluid with new fluid improves operation and extends the life of your differential.
From The Inside
About 4x4 Service
Every time your vehicle is in for a service we check the differential fluid to see if it is time for a flush. If the fluid is milky or dark, it is probably time for it to be serviced. Milky differential fluid is a symptom of water entering the mix, and dark fluid is a sign of old, dirty, burnt, and otherwise worn out lubricant.
Differential fluid flushes can be hard to give a general quote for, and that is because the labour requirements for each vehicle are drastically different. Some vehicles just have a drain to remove the fluid, some need pieces removed access the drain, and others need more complete disassembly to reach the necessary components. The fluid is a synthetic and often needs an additive if it is a limited slip differential, but your technician will be able to give you the inside scoop on what you need for your specific vehicle and why.
What are the Benefits?
The benefits of 4×4 gearbox and differential service are many, but most importantly you can expect to increase the life of your differential, saving you very expensive repairs down the line. Benefits of differential fluid flushing include:
- Extends the life of the differential
- Protects against rust and corrosion in the differential
- Cleans, cools, and lubricates components
- Helps avoid costly drive train repairs
