Your Driveline

The driveline of your vehicle is actually composed of several parts that connect and form an entire system. Here’s a quick run-through of those parts and what each does for your vehicle.

Driveshaft

The driveshaft is a long steel tube that connects to the transmission on one end and is connected to your car, truck, van or SUV’s wheels at the other end. When the transmission is in gear, the driveshaft transfers torque from the engine to your wheels so you can move.

Differential

The differential is what lets your wheels spin at different speeds. This is important because if all your wheels move at the same speed at the same time, you have less control when braking and accelerating. The speed differentials are necessary to keep your car from pushing your wheels too hard into the road, which would put a strain on your vehicle and can lead to premature wear and tear.

Axle Shafts

There are different types of axel rods, also known as shafts, that rotate your car’s wheels. But they don’t just move the wheels, they also support the weight of your vehicle and everything you pack inside it. The axle shafts are usually located at the front, rear and “stub” of your car. Here’s a bit more on axle shafts.

Rear Axle

The rear axle rotates with your car’s wheels and comes in two pieces known as half shafts. These pieces are connected by the differential and provide power from the engine to the driving wheels.

Stub Axle

The front axle needs to be particularly sturdy, so it is often made from carbon or nickel steel. There are four main parts that comprise this axle: beams, swivel pin, track rod and stub axle. Together, these pieces help you steer and absorb shock when you drive on uneven roads.

Front Axle

The stub axle is attached to the front axle with kingpins on one end, and on the other end, they’re attached to the front wheels. These axles, also called stud axles, help your car make angular movements when you’re steering around corners and making sharp turns.

U-Joints

The U-joints, also known as universal joints, are small parts that connect the driveshaft to differentials. They’re shaped like a cross with bearings at each end that can move laterally or side-to-side of the driveshaft. These joints connect the driveshaft to the transmission and also connect two driveshafts to each other in certain kinds of vehicles.

CCV Joints

CV joints, or constant velocity joints, attach to both ends of your drive shafts. There are a set of inner CV joints and outer CV joints. The inner joints connect to the drive shafts and transmission, while the outer joints connect drive shafts to the wheels. These joints transfer torque from the transmission to the drive wheels and your car’s suspension. To keep the CV joints healthy, they’re packed with grease and tightly sealed with either a plastic or rubber boot. If the boot isn’t damaged, these can last more than 300,000 miles.

Common driveline problems

There are a number of symptoms to reveal what’s wrong with the different parts of your driveline. If there’s something wrong with your driveshaft, you may experience:

  • Excess vibrations
  • Difficulty turning
  • Shuddering when accelerating
  • Rattling, scraping, squeaking or loud clunking under hood

If there’s something wrong with your differential, you’ll get different signs:

  • Unusual vibrations
  • Rattling/whirring
  • Oil leak beneath axles
  • Check Engine light comes on
  • Strong oil or burning smell

When your axle shafts start to give out, you’ll notice these symptoms:

  • Grease leak
  • Car won’t move
  • Strong vibrations at all speeds
  • Loud clanking, clunking or clicking

For your U-joints, you may experience:

  • Difficulties controlling car
  • Vibrating steering wheel
  • Shuddering while accelerating
  • Difficulty turning
  • Loud squeaking, clicking or knocking

And finally, for your CV joints, your vehicle may display:

  • Side-to-side shaking/vibrating when accelerating
  • Grease leaks from protective boot
  • Damaged boot
  • Clicking or popping sounds that get louder when turning

If your vehicle is displaying any of these worrisome symptoms, call 12th Street Auto Care Center right away. One of our certified mechanics will take a look at your driveline and offer an affordable repair or replacement for all broken, worn or irregular parts.
