Differential & Transfer Case Service

Your drivetrain is what lets your vehicle put power to the ground smoothly and safely. The differentials and transfer case work together so your wheels can turn at different speeds and direct power where it’s needed. At Brakes Plus, we service front and rear differentials as well as transfer cases, so your turning system and drivetrain stay in top condition.

Expert Service

The differential is a mechanical component on the axle that allows your left and right wheels to rotate at different speeds when turning. Without it, your car couldn’t corner smoothly. The transfer case comes into play on vehicles with both front and rear differentials. It directs power separately to each differential, doing for them what differentials do for the wheels.

When you schedule a differential or transfer case service, our technicians inspect these components, replace old fluid, and make sure the system is lubricated and protected against heat and wear.

Keep an ear out and watch for these common symptoms:

  • Howling sound when accelerating

  • Whirring noise when decelerating

  • Clicking or clunking at regular intervals

  • Banging or rumbling noises when turning a corner

  • Fluid leaking under the vehicle’s axles

  • Smell of burning oil

  • Vibration that increases with acceleration

  • Front or rear wheels seizing up

If you’re hearing or feeling any of these, it’s time to get checked before bigger problems develop.

A complete service is more than just a fluid change. At Brakes Plus, we:

  • Check for leaks and damage

  • Drain old fluid

  • Fill with the manufacturer-recommended new fluid

  • Reseal the differential cover (when applicable)

It’s a messy job, but one we’re happy to handle - so you don’t have to.

Differentials and transfer cases are filled with fluid that lubricates internal gears and dissipates heat. Over time, this fluid can become contaminated with particles, overheated, or even diluted with water. When that happens, the gears can lock up - causing your wheels to seize.

To prevent damage, have the fluid checked every 30,000 miles, or sooner if you notice any of the symptoms above. Regular maintenance keeps your drivetrain reliable and avoids expensive repairs, but your local Brakes Plus team is here to help.

Why It Matters

Most drivers don’t think about their differentials or transfer case until something goes wrong, usually with a strange noise or a sudden vibration. The truth is, these components do quiet but critical work every single time you drive. Without them, your car wouldn’t turn properly or transfer power smoothly to all four wheels.

Benefits of routine differential & transfer case service:

  • Protects against gear damage and seizing

  • Extends the life of drivetrain components

  • Keeps AWD and 4WD systems operating as designed

  • Prevents costly repairs from neglected fluid changes

  • Improves overall driving comfort and control

When maintained on schedule, your drivetrain runs quietly and efficiently so you can focus on the road instead of the noises under your car. Don’t wait for a howl or a rumble to tell you it’s time. Schedule your differential and transfer case service today and keep your vehicle turning smoothly.
