Parts for your 2010 Holden Colorado-Thrust bearing

2010 Holden Colorado thrust-bearing — purpose, fitment and servicing

Based on technical literature for the RC-series Holden Colorado — notably the Holden Colorado RC Service Manual (clutch and manual transmission sections), the Isuzu TFR/TFS (D‑Max) Workshop Manual 2008–2012 that shares the same platform, and Exedy Australia clutch fitment guides — manual‑transmission 2010 Colorados use a clutch release (thrust) bearing. Automatic models don’t have a serviceable clutch thrust bearing, as they use a torque converter and internal transmission thrust elements.

On the manual Colorado, the thrust bearing sits on the gearbox input shaft sleeve and is moved by the clutch fork via the hydraulic slave. When the driver presses the pedal, the bearing pushes on the pressure plate’s diaphragm fingers to disengage the clutch, allowing smooth gear changes without grinds. Its job is to turn axial pedal force into low‑friction, rotary-friendly movement at the pressure plate — quietly and reliably, even after a few hundred thousand kays of towing or farm work.

There’s no fixed replacement interval for the thrust bearing, it’s a “replace on condition” part. Because the gearbox has to come out to reach it, it’s standard practice to renew the thrust bearing whenever the clutch is replaced. Most reputable clutch kits for the Colorado include a new release bearing for exactly this reason.

• Common symptoms of a worn thrust bearing: rumbling or squeal with the pedal depressed, rough pedal feel, clutch notchy to disengage, or vibration through the pedal.
• If noise changes when the pedal is pressed, suspect the thrust bearing before the input shaft bearing.

Good workshop habits make a big difference. When the clutch is out, inspect and, if needed, replace related bits: pilot/spigot bearing, clutch fork and pivot, guide tube, rear main seal, and gearbox input seal. Use only a light smear of high‑temp grease on the guide tube and fork contact points, never on the friction surfaces. Bleed the clutch hydraulics and keep the fluid fresh per the service schedule (typically every two years) to protect the slave and master.

For clarity: the thrust bearing discussed here applies to manual 2010 Holden Colorados, automatic variants don’t use a clutch thrust bearing as a service item.

Does a 2010 Holden Colorado automatic have a thrust bearing?
Automatic Colorados don’t have a clutch thrust (release) bearing. They use a torque converter and internal bushings/thrust washers inside the auto trans, which aren’t serviced like a manual’s release bearing. If there’s driveline noise on an auto, the diagnostic path is completely different from a manual clutch issue.

How long does a thrust bearing last on a Colorado?
With sensible driving, they often run well beyond 150,000–250,000 km. Heavy towing, dusty conditions, riding the clutch, and lots of stop‑start can shorten life. If the clutch is due, replacing the thrust bearing at the same time saves paying for gearbox removal twice.

Can a noisy thrust bearing damage other parts?
Left long enough, a rough bearing can chew at the pressure plate fingers, mark the guide tube, and accelerate wear at the fork and pivot. In worst cases it can bind, making the clutch slow to disengage. That’s why a noisy or gritty bearing is worth sorting before it cascades into a bigger clutch job.
