Parts for your 2019 Holden Colorado-Universal joints

Universal Joints on the 2019 Holden Colorado: What You Need to Know

The 2019 Holden Colorado is a rugged and versatile ute built to handle tough Aussie conditions. When it comes to drivetrain components like universal joints, or U-joints as they're commonly called, it's worth understanding whether they play a role in this vehicle and how to look after them if they do. After consulting technical sources and the official specifications, it's clear that the 2019 Holden Colorado does indeed use universal joints as part of its drivetrain setup.

So, what exactly are universal joints, and why are they important for a vehicle like the Holden Colorado? Universal joints are mechanical connectors that allow the driveshaft to transmit power from the transmission to the differential while accommodating the movement and articulation between these parts. This flexibility is crucial, especially in vehicles like utes or 4WDs where the suspension travels up and down over uneven terrain. Without universal joints, the driveshaft would be rigid and prone to failure or damage as the angles between components shift.

Specifically, the Holden Colorado's drivetrain incorporates universal joints to connect the transmission output shaft to the driveshaft, and then the driveshaft to the rear differential. These joints handle the variations in angles that occur as the vehicle flexes, particularly when driving off-road or over bumps. This provides a smooth transfer of power, minimising vibrations and reducing stress on the drivetrain components.

When it comes to maintaining these universal joints on a 2019 Holden Colorado, regular servicing is essential to keep everything running smoothly. U-joints are subject to lots of torque and constant movement, so they can wear out due to friction, lack of lubrication, or corrosion over time. Most U-joints in the Colorado are greasable, meaning they come with a grease nipple that allows fresh grease to be pushed in, flushing out old lubricant and contaminants.

Service intervals for universal joints depend on how much and what type of driving the vehicle does. If the ute mostly sticks to the bitumen for everyday driving, it might be fine to service the U-joints every 30,000 to 50,000 kilometres. However, if the Colorado is used for towing, off-roading or in dusty, muddy environments, more frequent inspection and greasing are advised. Stressed U-joints may show signs like noticeable clunking noises when shifting from drive to reverse or a vibration that increases with vehicle speed.

When inspecting universal joints during regular servicing, mechanics look for several key indicators of wear:

• Excessive play or looseness in the joint
• Rust or corrosion build-up around the components
• Leaking grease or dry areas on the cross and bearing caps
• Visible cracks or damage to the joint housing

If any of these signs are present, it's best to replace the universal joint promptly. Driving on worn or failing U-joints can cause more damage to the driveshaft and even lead to drivetrain failure, which is a costly repair and very inconvenient. Replacement involves removing the old joint, pressing in a new one, and ensuring everything is well greased and aligned before reassembly.

For those who like to DIY, lubricating the universal joints is a straightforward job if the U-joints have grease nipples. Using high-quality grease suitable for chassis and drivetrain components helps extend the life of the joints. It's a good idea to check the owner's manual or service guide for the recommended type of grease and the exact procedure to follow. And as always, ensure the vehicle is safely supported when working underneath.

In a nutshell, universal joints are a key part of the 2019 Holden Colorado's drivetrain system allowing smooth power transfer despite suspension movement. They take a fair bit of stress, so keeping them lubricated and checking for signs of wear should be part of every ute owner's regular maintenance routine. Whether the Colorado is your daily drive or weekend explorer, paying attention to U-joints will help avoid unexpected breakdowns and keep the vehicle running at its best for years to come.
