If you own a rear-wheel-drive car, truck, or SUV then your vehicle is equipped with a differential. Like any other component on your car, maintaining your differential is an important aspect of keeping your vehicle reliably on the road. From Harold's Used Auto Parts Inc in Philadelphia, PA, here’s what you need to know.

Your differential is responsible for a few different things. It attaches your wheels to the car, translates input from the transmission into motion at the wheels, and allows your wheels to turn at different speeds to accommodate turning. Much like your engine or transmission, it consists of constantly moving parts, bearings, and is filled with fluid, which needs to be serviced at regular intervals.

You probably keep track of oil changes and transmission fluid flushes, but most people don’t consider their differentials very often. While it is a simpler system that requires less maintenance than an engine or transmission, ensuring it’s well lubricated and operating smoothly is no less important.

To keep your differential in good shape and reliable, look no further than our professional technicians. No matter your vehicle maintenance or repair needs, we’ve got your back. For the best auto service shop in Philadelphia, PA, call or stop by Harold's Used Auto Parts Inc today.
