2010 Mazda Premacy Thrust Bearing — What It Does and When to Sort It

Based on technical sources such as the factory Mazda Premacy/Mazda5 2010 workshop manual (clutch section) and Mazda’s electronic parts catalogue, a thrust bearing is indeed used on this model. Manual-transmission Premacy variants have a clutch release (thrust) bearing, and all engines use crankshaft thrust bearings in the bottom end. Automatic models don’t have a clutch release bearing, but the engine thrust bearings are still present as internal components.

On a 2010 Mazda Premacy with a manual gearbox, the thrust bearing’s job is to press smoothly against the pressure plate’s diaphragm spring when the driver puts a foot on the clutch. That light, precise contact lets the clutch disengage cleanly so gears can be selected without graunching. Depending on engine and market, Mazda fitted either a conventional release bearing with a fork and an external slave cylinder, or a concentric slave cylinder (CSC) that integrates the bearing around the input shaft. Either way, the idea is the same: quiet, low-friction thrust in the exact direction the clutch needs it.

It’s not a serviced item in the usual sense, but it does wear. Common signs it’s on the way out include a chirp, squeal, or rumble that appears when the clutch pedal is pressed and disappears when it’s released, a notchy or heavy pedal feel, or poor clutch release. If the bearing is noisy, the smart move is to replace it when the gearbox is out—ideally as part of a full clutch kit (disc, pressure plate, release bearing, and pilot/ spigot bearing). That approach saves on repeat labour and keeps the whole system in balance.

Good practice during replacement:

• Inspect the fork, pivot ball, guide tube, and input shaft splines, renew worn bits.
• Use the correct high-temp grease sparingly on contact points—no overdoing it.
• Check the rear main seal and gearbox input seal while you’re there.
• Bleed the hydraulics properly (especially if it’s a CSC) and follow torque specs from the workshop manual.

There’s no set interval—many last well beyond 150,000–250,000 kilometres, depending on driving style. Avoid riding the clutch, keep the hydraulics leak-free, and the bearing will typically live a long, quiet life. For automatic Premacy models, the clutch thrust bearing doesn’t apply, engine crankshaft thrust bearings are internal and only addressed if there’s excessive end float during engine repair.

Popular questions

Does a 2010 Mazda Premacy have a thrust bearing?
Yes. Manual versions have a clutch release (thrust) bearing, and all engines have internal crankshaft thrust bearings. Automatics don’t use a clutch thrust bearing but still have engine thrust bearings that aren’t routine service items.

What are the symptoms of a failing Premacy thrust bearing?
Listen for a chirp, squeal, or rumble that appears when the clutch pedal is pressed and fades when released. You might also notice a heavier or notchy pedal and gears getting harder to select cleanly. If those show up, plan for a clutch and bearing job.

Should the thrust bearing be replaced with the clutch?
Absolutely. It’s best practice to replace the release bearing whenever the clutch is renewed. It adds little cost during the same labour and helps prevent noise or failure soon after a new clutch goes in.
