Your car’s driveshaft is what transmits the engine’s rotational power, or torque, to the front, rear, or both front and rear wheels of the car through the transmission. Driveshafts are most commonly used on front-engined rear-wheel-drive cars. Some of the issues you may have to deal with are: abnormal noises, difficulty turning, intense vibrations, and any movement from or visible rust around the universal joint (U-joint).
When it comes to fixing your car’s driveshaft, the sooner the better. Early detection can save the machine from total replacement. But when the driveshaft is already failing, not replacing it as soon as possible can be dangerous. A few of the tools needed for driveshaft replacement are jacks and jack stands. This is a job that you can DIY but we highly recommend leaving it up to a professional.
Driveshaft shortening is a procedure where the driveshaft must be shortened due to transmission change, adjustment of the car’s height, rear end change, or just to fit into the car.
Technically, you cannot stretch a driveshaft to make it long. This process is done by replacing the tube in your driveshaft by removing both weld yokes and replacing it with a new tube of the proper length. The driveshaft must be balanced to avoid vibrations.
Driveshaft balancing is usually performed after you do driveshaft shortening, driveshaft lengthening, and universal joint replacement. If your car’s driveshaft is out of balance, some causes can be worn or loose u-joints and clamps, missing balancing weights, severe rust, etc.
You can save more than half the price when you rebuild your car’s driveshaft compared to when you replace it. With driveshaft rebuilding, you only replace the parts that need replacement and not the whole component.
