Everything You Need to Know About CV Joints

What Is a CV Joint?

A CV joint (short for Constant Velocity joint) is an important part of your car’s drivetrain. It links your gearbox to your wheels, making sure power flows smoothly, even when your wheels turn or drive over bumps.

If you’ve ever wondered, “What is a CV joint?” think of it as the flexible connection that keeps your car moving safely. Without it, your wheels can’t rotate properly, and your vehicle won’t drive correctly.

In South Africa, every front-wheel-drive car, as well as many rear- or all-wheel-drive vehicles, relies on CV joints to stay on the road safely.

Types of CV Joints

There are two main types of CV joints in most cars:

Inner CV Joint

The inner CV joint connects the driveshaft to the transmission, also known as the gearbox. It’s closest to the engine and sits inside a protective boot filled with grease. Its job is to handle motion from the engine while keeping the wheels turning smoothly.

Outer CV Joint

The outer CV joint connects the driveshaft to the wheel hub. It lets your wheels turn while keeping a constant power flow. This is especially important when driving on uneven or rough roads in South Africa.

Both joints rely on a CV joint boot to keep grease in and dirt out. A torn boot can quickly damage the joint, causing CV joint noise when driving straight or other issues.

Common Signs Your CV Joint Might Be Failing

Pay attention to these warning signs so you can fix problems before they become serious:

• Clicking or popping while turning: Usually comes from a worn outer CV joint.
• Knocking or vibration when driving straight: Often a sign of a failing inner CV joint.
• Grease splattered around the wheel area: Could mean a torn CV joint boot.
• Your car suddenly stops driving smoothly: Ignoring early signs can lead to a broken CV joint, leaving your car undrivable.

CV Joints in Popular South African Cars

If you’re the proud owner of a Polo Vivo, Toyota Corolla, VW Polo, or Mazda 323, chances are you’ve experienced the little nagging noises that make you wonder if something is wrong. City traffic in Johannesburg and Pretoria can be relentless on Polo Vivo CV joints, and heavy stop-start driving may leave you anxious about sudden breakdowns. Even a reliable Toyota Corolla can surprise you if worn joints are ignored, while VW Polos often show signs of wear on uneven or pothole-prone roads, creating that unsettling clicking when turning. Older Mazda 323s, though dependable, can suddenly demand attention after years of use, turning a minor noise into a stressful repair if not addressed early.

The reality of car trouble is real, and many drivers hear the clicks, hope it’s nothing, and delay fixing it. But recognising the signs early, whether it’s a slight knock when driving straight or a subtle vibration from your inner CV joint, not only saves money but also spares you the frustration and stress of being stranded on the side of the road.
