Let’s get straight to it. You’re driving in a snowstorm, and your truck’s four-wheel drive stops working—there’s no traction for your front wheels. Next thing you know, you’re stuck with a big repair bill that could have been avoided by simply prioritizing fluid maintenance.
For example, in this case, the drivetrain fluids had not been serviced, causing the gears inside the front differential to wear down. Drivetrain fluids are often overlooked by both auto repair shops and vehicle owners. Most drivetrain fluids need to be serviced between 50,000 and 100,000 miles. However, depending on how frequently the vehicle is used, fluids might need to be changed more often.
Drivetrain fluids are not often checked or recommended for inspection. However, if you use your truck frequently—especially in four-wheel drive—and the fluid condition is poor, it can cause significant wear and tear. Smaller vehicles also have similar drivetrains with multiple fluids that require regular maintenance.
Differential oil and transfer case fluid services are far cheaper than having to repair or replace parts. Additionally, ensuring the correct manufacturer-recommended fluids (and additives) are used is crucial, as using the wrong fluids can cause major issues.
To make a long story short, prioritize fluid service for your vehicle to avoid costly repairs down the road.
