Parts for your 2012 Holden Colorado-Driveshafts

2012 Holden Colorado Driveshafts

Driveshafts are absolutely relevant to the 2012 Holden Colorado. Technical sources including the Holden RG Colorado Workshop Manual (Driveline/Propeller Shaft and Front Drive Axle sections), the RG Colorado Owner’s Handbook maintenance schedule, and the 2012 Isuzu D‑MAX Workshop Manual (platform twin to the Colorado) all detail the propeller shaft, universal joints, centre support bearing, and—on 4x4 models—front CV driveshafts and a front prop shaft. Those documents confirm the 2012 Colorado uses a rear propeller shaft on all models and additional front driveline components on 4x4 variants.

On the road or paddock, the driveshafts carry torque from the gearbox or transfer case to the diffs. In 2WD Colorados, a rear prop shaft with uni joints and often a centre bearing handles the load. In 4x4 models there’s also a front prop shaft and a pair of CV driveshafts to the front wheels, letting the ute put power down while the suspension moves.

A healthy shaft runs smooth and quiet. If there’s a clunk on take‑off, a shudder between 60–100 km/h, a rumble under load, or clicking when turning in 4x4, it’s time for a look. Common wear points are uni joints, the centre support bearing, the slip joint splines, and CV joints/boots up front. Torn CV boots or red dust around uni joints are red flags.

As part of regular servicing, it’s smart to:

• Inspect the prop shaft, centre bearing, and uni joints for play, rust powder, or binding.
• Check front CV boots on 4x4s for splits and grease sling, replace boots early to save the joint.
• Verify flange bolts are tight and correctly torqued, don’t overgun them with a rattle gun.
• After water crossings or off‑roading, re‑inspect—grit and immersion accelerate wear.

Many OE uni joints are sealed, replace them if they’re notchy or loose. If greasable joints are fitted, hit them with quality grease at service time and keep the slip yoke splines lightly lubricated. There’s no fixed replacement interval—go by condition. If the shaft’s been apart, mark its orientation and have it balanced by a driveline specialist to avoid vibration. Lift kits can alter angles, so check pinion angle and centre bearing alignment on modified rigs.

Don’t ignore vibration, it can take out tailshaft seals and diff or transfer case bearings. Quality parts, correct torque from the service manual, and a quick look every 10–15,000 kilometres keep a Colorado’s driveline sweet for the long haul.

Popular questions about 2012 Holden Colorado driveshafts

What symptoms point to worn driveshafts or uni joints on a 2012 Holden Colorado?
Drivers often notice a clunk when shifting from reverse to drive, a shudder on acceleration, or a steady vibration at highway speeds. You might also hear a rhythmic thump that changes with road speed. On 4x4s, clicking on full lock can indicate a front CV joint on the way out. Any red dust around a uni joint cap or movement at the centre bearing is a giveaway.

How often should the driveshafts be inspected?
A quick check every service—roughly 10–15,000 km or 6–12 months—does the trick for most utes. If the Colorado works hard, tows, sees corrugations, water crossings, or beach work, inspect more frequently. Look for boot splits, loose or rusty uni joints, centre bearing rubber cracking, and any fresh oil around the output or pinion flanges.

Can a vibrating Colorado prop shaft be balanced, or does it need replacing?
Light vibrations from minor imbalance can often be fixed with a professional balance, provided the tube is straight and the uni joints and centre bearing are healthy. If the shaft is bent, dented, or the yokes are worn, replacement or rebuild is the better call. Always refit the shaft in its original orientation and torque the flanges correctly to avoid introducing a new vibration.
