Parts for your 2014 Holden Colorado-Thrust bearing

2014 Holden Colorado thrust-bearing: what it is, where it lives, and when to sort it

Technical sources including the Holden RG Colorado workshop manual (2012–2016) and GM/ACDelco parts catalogues confirm the 2014 Colorado does use thrust bearings. Every engine has a crankshaft thrust bearing integrated into the main bearing set, and manual-transmission Colorados also use a clutch release (often called “thrust”) bearing. On many manual models this release bearing is integrated with the concentric slave cylinder (CSC) inside the bellhousing. Automatic variants don’t have a clutch thrust bearing, but still rely on the engine’s crankshaft thrust bearing.

In everyday terms, the clutch thrust bearing lets the clutch engage and disengage smoothly when the pedal’s pressed, transferring the pedal force to the pressure plate without nasty friction or noise. The engine’s thrust bearing controls end-float of the crankshaft so it can’t walk forwards or backwards under load.

• Common signs the clutch thrust bearing’s tired: a whirring or growl with the clutch pedal depressed, a change in pedal feel, notchy engagement, or fluid seepage if the CSC is leaking.
• Engine thrust bearing issues are rare, warning signs include abnormal end-float, metallic noises that change with load, or clutch/driveplate witness marks during deeper diagnosis.

There’s no routine service interval for a thrust bearing, it’s a replace-on-condition part. For a manual Colorado, it’s best practice to replace the release/thrust bearing whenever the clutch is out, because gearbox removal is the bulk of the labour. If fitted with a CSC, replace the complete unit, not just the bearing.

Smart servicing on a manual 2014 Colorado looks like this:

• Fit a quality clutch kit (pressure plate, friction disc, release/thrust bearing, CSC if applicable) and inspect/replace the spigot/pilot bearing.
• Check the flywheel face and rear main seal, machine or replace as needed.
• Bleed the hydraulic system with the specified brake fluid (DOT rating as per cap/manual) and inspect the master cylinder and lines.
• Torque fasteners to spec, keep grease off the friction surfaces, and verify clutch pedal free play and bite point.

For autos, keep engine oil quality up and investigate any end-float concerns promptly, while crank thrust bearing failures are uncommon, clean oil and correct idle/line pressures help everything live a long life.

Does a 2014 Holden Colorado have a thrust bearing?

Yes. All engines have a crankshaft thrust bearing. Manual models also have a clutch release (thrust) bearing, often integrated with a concentric slave cylinder inside the bellhousing. Automatic models don’t use a clutch thrust bearing.

How long should the clutch thrust bearing last?

It often lasts the life of the clutch. Riding the clutch, heavy towing, heat, contamination, or hydraulic issues can shorten its life. If the gearbox is out for any reason, replacing the bearing/CSC with the clutch kit is wise insurance.

Can just the thrust bearing be replaced on its own?

It can, but it’s not recommended. Because most of the cost is labour to remove the gearbox, it’s more cost‑effective to replace the full clutch kit (and CSC if fitted) and inspect the flywheel and seals at the same time.
