Is your Cummins, Powerstroke, or Duramax diesel a four-wheel drive? At TAG Automotive Repair in Flagstaff, AZ, our goal is to help you maintain your four-wheel drive so that it can last you for years to come. Our professional technicians at TAG Automotive Repair are here to make sure your truck stays ready for anything.

4X4 systems, like any other system on your truck, require regular maintenance. Compared to an engine or transmission, they’re pretty hassle-free, but that means it’s important to not forget about keeping an eye on it every once in a while. Your transfer case, differentials, and the mechanisms that engage or disengage 4WD all work together to keep your truck going on or off-road.

Bearings, seals, and fluids are the most important aspects of all these components. Keep an eye out for leaks - if the fluid runs dry, you might not notice until it’s too late. Listen for irregular noises or shifting difficulties, and have them serviced immediately if one arises. You’ll save your Chevy, Ram, or Ford pickup from extensive damage in the long run. It’s especially important to maintain your 4X4 system if you use your truck much off road, or in inclement conditions.

No matter your repair and maintenance needs, we’ve got you covered. For the best diesel service shop in Flagstaff, AZ, call or stop by TAG Automotive Repair today.
