Universal Joints | Regularly Check Driveline Components

The driveline components — universal joints are built to deliver peak performance. Transmitting torque from your truck's transmission to its axles while adjusting to changes in driveshaft length is a tough balance. Properly functioning u-joints smooth things out by providing flexibility between your prop shaft and axles, even in the most grueling road conditions.


Rising to such a difficult challenge is a full-time job. Your u-joints work non-stop while your truck is on the road, and this constant movement and stress can cause wear and tear. U-joint problems can lead to driveline failure and thousands of dollars in repairs.


Good news. With proper preventive maintenance, most u-joint issues can be averted. Most of the time, u-joints fail due to inadequate lubrication. 


Following a multi-point lube check at your truck dealership, factory-trained technicians will use lubricants that are pure truck – designed to keep your u-joints and other critical components doing their job. 


If you want to install maintenance-free u-joints as an alternative to greasing, you'll need components that meet Mack's high performance standards. For example, select genuine heavy-duty u-joints are offered with service-free options, in addition to the standard reliable options. 


Both are engineered to closely control tolerances, creating a tighter fit, better balance capability and reduced driveline vibration.


Operating your heavy-duty truck with excessive driveshaft angles could also contribute to premature u-joint failure. 


It is recommended that u-joint angles should be no greater than 3 degrees, and the difference in angles between front and rear u-joints on the same driveshaft should not exceed 1 degree. 


The higher the u-joint angle, the shorter the life of the joint.


Here are four signs your u-joints may be damaged or going bad:


1.Loud clunks in the driveshaft when shifting gears
2.Vibrations/roughness/shudders during acceleration or deceleration
3.Grease leaking out of end caps
4.Play in the driveshaft


All driveline components should be closely examined at regular service intervals to ensure maximum longevity. 


We have first-class production line and strict management system.
