⚙️ Dogbone
A simple driveshaft with pinned ends shaped like a dog bone — cheaper and more common than a CVD, but doesn't transfer power as smoothly at steep angles.
What it actually does
A dogbone is the simple driveshaft with a bone-shaped end that sits in a cup on the diff outdrive. It is cheap, strong and easy to replace, which is why it is standard equipment on so many models despite being less refined than a CVD.
In practice
Because the joint is a simple pin in a cup, drive is slightly uneven at large angles — noticeable at full steering lock on the front of a car, largely irrelevant at the rear. They also plunge in and out as the suspension moves, which is what makes them tolerant of long travel.
Worth knowing
Dogbones and their cups wear together. Replacing a worn bone into a worn cup gives you a joint that pops out under load, so inspect both.
