Your factory GM driveshaft, sometimes called a drivetrain, has the important job of transforming torque and engine rotation energy into motion. Shift into drive, and your driveshaft transfers that energy to the auto parts that get you moving. Your GM car or truck has one of four drivetrain types. One is rear-wheel drive. Here, a long driveshaft connects at one end to your transmission. At the other end, it connects to your differential via universal joints or "U-joints." This setup enables your rear wheels to deliver the motive power. Two other types of driveshafts are four-wheel drive and all-wheel drive. These systems have two of them. One is the same drivetrain you can find on a rear-wheel drive vehicle. The other is a second front driveshaft connected by U-joints to both your front differential and your transfer case. Every wheel participates in powering the drive here. The last driveshaft type is front-wheel drive. In this case, your front wheels deliver power, and you can find all drivetrain components installed in the front of your vehicle. Instead of linking using universal joints, however, this setup uses constant velocity joints, known by the shorthand "CV joints." The signs and symptoms of a bad driveshaft are many. If you have trouble making turns, your undercarriage vibrates, or you hear a loud clunk when shifting, you could have a worn or failing U-joint or coupler. These can sometimes indicate a bad carrier bearing, too. Either way, the situation can lead to further damage to drivetrain components. Shuddering when accelerating, on the other hand, can mean your U-joint is loose. Hearing clicks or knocks, however, probably mean a worn or failing CV joint. Luckily, you can purchase the best GM driveshaft for any repair or replacement project straight from the factory. Order yours online today through us, right here!
