Parts for your 2015 Holden Colorado-Universal joints

2015 Holden Colorado universal joints (U-joints): what they do and how to look after them

Universal joints are absolutely relevant to the 2015 Holden Colorado. The RG Colorado (2012–2016) uses a rear propeller shaft with cross-and-bearing (cardan) universal joints at each end, and some variants run a two-piece tailshaft with a centre bearing. This is documented in the Holden/GM RG Colorado Workshop Manual under Driveline/Propeller Shaft, and supported by OEM/aftermarket catalogues from ACDelco, Dana Spicer and GMB that list direct-fit U-joints for this model. The 4x4 front half-shafts use CV joints, while the rear driveline relies on U-joints.

On the 2015 Colorado, the universal joints sit at the ends of the tailshaft, allowing the shaft to transfer torque to the rear differential while coping with suspension movement and angle changes. They’re small but critical, a tired U-joint can cause vibration, clunks, and in worst cases, driveline failure. For owners who tow, tour, or bounce down corrugated tracks, keeping these joints sweet is cheap insurance.

Servicing is straightforward. At each service interval (or every 10,000–15,000 km if the ute works hard), the U-joints should be inspected for play and smooth movement. Many factory joints are sealed, if the Colorado has greasable replacements fitted, a quick shot of quality lithium-moly grease until fresh grease appears at all four seals does the trick. Any red dust staining around the caps, a regular low-speed squeak, a clunk on take-off, or noticeable vibration under load are all signs they’re on the way out.

When replacement is due, it pays to use quality branded joints and new circlips. Mark the tailshaft and flanges before removal to maintain balance and phasing, support the shaft to avoid stressing the centre bearing (if fitted), and torque the strap/bolt hardware to factory spec. If one rear U-joint has failed, it’s smart practice to replace the pair, then recheck the tailshaft balance and the centre bearing condition. After heavy water crossings or beach work, an extra inspection and, if applicable, a re-grease are well worth it.

Done right, fresh U-joints restore that smooth, quiet run-up through the gears and keep the Colorado’s driveline reliable for the long haul.

• Common symptoms: take-off clunk, low-speed chirp/squeak, vibration at highway speeds, visible play at the yoke.
• Service tips: inspect every service, grease if fittings exist, replace in pairs, maintain phasing and balance.

Popular questions

How often should the 2015 Colorado’s U-joints be serviced?

They should be checked at every routine service. If the vehicle tows, does beach work, or sees corrugations, inspect every 10,000–15,000 km. Grease them if greasable joints are fitted, sealed OEM-style joints are inspect-and-replace items.

What are the tell-tale signs the U-joints need replacing?

Look for a clunk when shifting from reverse to drive or on take-off, a rhythmic squeak at low speed, or a vibration that worsens under load. Rust-coloured dust around the bearing caps or any detectable play at the yokes is a giveaway.

Does the 4x4 front end use U-joints as well?

No. The 2015 Colorado’s front half-shafts use constant velocity (CV) joints. The universal joints are on the rear propeller shaft, some models also have a centre bearing supporting a two-piece tailshaft.
