Parts for your 2016 Holden Colorado-Thrust bearing

2016 Holden Colorado thrust-bearing — what it does and when to replace it

Technical references confirm a thrust-bearing is relevant and used on the 2016 Holden Colorado. The GM Holden RG Colorado Service Manual (Clutch and Engine Mechanical), ACDelco and Exedy clutch catalogues for RG Colorado (2012–2016), and GM Global Service Information for the 2.8L Duramax LWN note two thrust-bearing applications: a clutch release (thrust) bearing on manual models—commonly integrated into a concentric slave cylinder—and an internal crankshaft thrust bearing within the engine’s main bearings. Automatic models don’t use a clutch release bearing.

On a manual 2016 Colorado, the thrust-bearing’s job is simple but vital: it transfers pedal force smoothly to the pressure plate’s diaphragm, allowing clean clutch disengagement without chewing out those diaphragm fingers. Because it spins only when the clutch is pressed, a healthy bearing keeps gear changes slick and quiet. Many RG Colorados use a concentric slave cylinder (CSC) with the release/thrust bearing built in, so it sits inside the bellhousing—out of sight, but absolutely central to how the ute drives.

Tell-tales of a tired thrust-bearing include a whirring or squeal when the pedal’s depressed, a notchier shift feel, clutch bite that’s inconsistent, or fluid leaks from the bellhousing area if the CSC seals are on the way out. If any of that shows up, it’s best practice to replace the bearing (and CSC) together with a new clutch kit. Labour overlaps are significant because the gearbox has to come out, doing the disc, pressure plate, release bearing/CSC, and pilot bearing as a set saves a second teardown. While there, inspect the flywheel face, rear main seal, and gearbox input seal, and follow the service manual for torque specs and alignment.

There’s not much day‑to‑day maintenance for the thrust-bearing itself. Keeping the hydraulic system bled with the specified brake fluid and not riding the clutch (foot off at the lights, select neutral) will extend its life. If the clutch is due, plan on a new CSC/release bearing every time—parts cost is modest next to the labour.

For completeness, the engine’s crankshaft thrust bearing (part of the main bearing set, typically at the centre main) manages crank end‑float. It’s not a routine service item and is only addressed during engine repair or if abnormal end‑float is diagnosed.

Popular questions about 2016 Holden Colorado thrust-bearing

Does a 2016 Colorado have a thrust-bearing?
Yes. Manual versions use a clutch release (thrust) bearing—often as part of a concentric slave cylinder. All engines also have a crankshaft thrust bearing internally. Automatic models don’t have a clutch release bearing.

When should the thrust-bearing be replaced on a 2016 Colorado?
Typically whenever the clutch is replaced, or sooner if there’s noise with the pedal depressed, rough engagement, or evidence of hydraulic leaks from the bellhousing area. Because the gearbox must be removed, replacing the release bearing/CSC with the clutch kit is the smart move.

What fluid does the Colorado’s clutch system use?
The hydraulic clutch shares brake-type fluid as specified by the vehicle’s cap and service manual. Using the correct spec and flushing at service intervals helps keep the concentric slave cylinder and release bearing happy.
