Universal Joints

When your driveline needs to transfer power smoothly, you do not mess around with worn-out parts. A universal joint keeps the shaft turning clean without shuddering or binding. At MaxiPARTS, we stock a tough line-up of uni joints options built for commercial trucks across Australia.

Why universal joints matter

Movement in the driveline puts a lot of pressure on your joints. When a universal joint starts to fail, you feel vibration, clunks, or harsh movement under load. It can damage the shaft, the gearbox or the diff. A good joint keeps power flowing steady. It also helps your truck stay roadworthy and safe. If you run long distances or heavy loads, strong uni joints make a big difference.

Types of universal joints available

Choosing the right joint often comes down to size, design and the type of driveline you are running. We carry a wide range of universal joint in Australia to suit different trucks and shaft setups.

Cross and bearing universal joints

Cross and bearing joints are the most common setup. They use a central cross with bearings on each end to let the shaft move while staying aligned. They handle strong torque and constant rotation. This style suits most heavy trucks and commercial driveline layouts.

Heavy-duty universal joints

Some trucks need extra strength. Heavy-duty u U-joint designs use stronger caps, a reinforced cross and tighter tolerances. These hold up under harsh use on highway rigs, road trains or trucks working rough sites.

Greasable vs sealed uni joints

Greasable joints suit operators who like to service their gear. They allow fresh grease and longer life when maintained. Sealed joints are low maintenance and suit trucks with tight servicing windows. The choice depends on how you run your vehicle.

Understanding universal joint load and performance

A universal joint is built to handle torque, movement and vibration. Using a joint below spec can lead to rapid wear or driveline failure. At MaxiPARTS, our joints are built strong and designed for Australian conditions. You get stable performance even under long hours, steep climbs or heavy towing.

Choosing the right universal joint for your truck

When you are picking a joint, think about:

• The driveline series and cap size

• How much torque your truck puts through the shaft

• Whether you want a greasable or sealed joint

• Your operating conditions and load cycles

• How often you service your driveline

FAQs

How do I know if my universal joint is failing?

You may feel vibration, hear clunks, or notice movement in the shaft when changing load.

Can I drive with a worn uni joint?

It is not safe. A failing joint can break the shaft and damage the gearbox or diff.

Do all trucks use the same size u joint?

No. Universal joints come in different series and cap sizes. Always match the size listed for your driveline.

Should I choose a greasable or sealed universal joint?

Greasable joints suit regular servicing. Sealed joints work well for trucks with longer service intervals.

How long does a universal joint last?

Life varies with load, driving conditions and maintenance. Inspect joints during routine servicing and replace at the first sign of wear.
