At Mark's Super Service Center in North Charleston, SC, we understand that no matter how well something is maintained, everything breaks eventually. Fortunately, our team of expert mechanics can repair just about anything, saving your business a lot of money in the process.

A commonly replaced item that can often simply be fixed instead is the rear end or differential. The differential has a lot to handle; not only does it have to manage all the power and torque created by the engine, but it must also be able to endure moving thousands of pounds of cargo. While most differentials are incredibly reliable, they do break from time to time. Gears and bearings wear out as a result of friction and fluid leaks, or of normal wear and tear from the burden of hauling so much weight. Axles can fracture or break as well, leaving a truck stranded.

However, differentials aren’t all that complicated, and can typically be rebuilt or repaired. New gears, bearings, axles, or seals can be installed, extending the life of a rear-end by many thousands of miles, and sparing the expense of a new one.

When a differential is going bad, there are a variety of symptoms. Fluid leaks around the wheels or under the differential indicate bad gaskets and seals. Howling or grinding sounds while driving, as well as bucking, or loud popping or clunking noises when accelerating or decelerating, are signals of worn internal gears. Sometimes, a truck may not move at all, accompanied by some sort of grinding or pounding noise when the truck is in gear, meaning an axle has broken or gear has stripped out completely.

If one of your trucks is in need of differential repair, don’t hesitate to have it inspected by one of our technicians as soon as possible. The sooner the problem is corrected, the chances for further damage decrease and a stranded truck on the side of the road can be avoided as well.
