Differential repair is comprised of several different tasks. This three part series will explore how your differential works and what repairs it may need.
Differential Fluid Replacement
One of the most basic repairs that a repair shop can do for you is replace your differential fluid. This is one of the most neglected fluids in your vehicle. Most people know that cars need to have their oil changed, and occasionally power steering fluid, but the differential’s often forgotten.
While differential fluid isn’t replaced as frequently as oil is, if you fail to do it, you’re going to lose lubrication, which considering that a differential is under pressure is fairly serious. The gears in your differential are specially hardened steel, and if they break, you could be looking at a costly repair job.
Differential Fluid Replacement and Your CarMuch like motor oil, over time, differential fluid can get a bit dirty and start to lose lubrication properties. A car that needs to have its differential fluid replaced will start to exhibit some problems when it is turning. The gears in your differential provide energy to your vehicle’s axles, which in turn spin the wheels at the right speed every time you hit the accelerator, and/or turn your steering wheel. Imagine if that stopped working right.
If you are doing your own differential fluid change, make sure you follow all of the instructions in your car’s owner’s manual. Don’t overfill your fluid, and make sure that you have put all plugs back in tightly. If you don’t you could find your differential burning up because there is no more fluid in the case.
If you don’t know how to replace differential fluid, understand that like all auto repairs, there is a big learning curve. You are probably better off getting your car into a differential repair shop instead.
