Parts for your 2013 Mazda 3-Thrust bearing

2013 Mazda 3 thrust bearing — what it is, why it matters, and when to replace it

After checking recognised technical sources — Mazda 3 (BL) Workshop Manual clutch and manual transaxle sections, the Skyactiv-G (PE-VPS) and MZR engine bearing specifications in the workshop manual, plus the Mazda Electronic Parts Catalogue — a thrust bearing is indeed relevant to the 2013 Mazda 3. Manual-transmission models use a clutch release (thrust) bearing, and all fitted engines use crankshaft main bearings with thrust faces to control end float. Automatic models don’t have a serviceable clutch release bearing.

For owners of manual 2013 Mazda 3s, the thrust bearing most people talk about is the clutch release bearing. Its job is simple but critical: when the clutch pedal is pressed, the bearing lets the pressure plate’s diaphragm spring be pushed smoothly without grinding. That keeps pedal feel light, take-up consistent, and shifts clean. When it wears, the car can start chirping or squealing as the pedal goes down, the pedal can feel rough or notchy, and engagement can get a bit ordinary.

Replacement is a gearbox-out job, so it’s smart to treat the thrust bearing as part of a complete clutch service. Most workshops will recommend:

• Replace the clutch kit (friction disc, pressure plate, release/thrust bearing, and pilot bearing/bush if fitted).
• Inspect the clutch fork, pivot, guide tube and input shaft splines, clean and lightly lube where specified by Mazda.
• Check the rear main seal and gearbox input seal while you’re there — cheap insurance with the box out.
• Bleed or replace the clutch hydraulic fluid, inspect the slave cylinder and master for leaks or drag.

There’s no set time or kilometre interval just for the thrust bearing, it’s replaced on condition or with the clutch. Driving style, stop–start traffic, heat, and contamination all play a part. If there’s noise only when the pedal is depressed, that points squarely at the release bearing. Noise with the pedal up is more likely input shaft or gearbox bearings.

Worth noting as well: the 2013 Mazda 3’s engines use thrust faces in the main bearings to manage crankshaft end float. Those aren’t routine service items and are only addressed during engine rebuilds or if there’s confirmed excessive crank walk.

Popular questions

Does a 2013 Mazda 3 have a thrust bearing?
Yes. Manual models use a clutch release (thrust) bearing, and every engine variant has crankshaft thrust faces within the main bearings to control end float. Autos don’t have a serviceable clutch release bearing, so the term usually refers to the clutch bearing on manuals.

What are the signs the thrust bearing is failing on a Mazda 3?
Typical clues are a squeal, chirp, or grinding sound when the clutch pedal is pressed, a rough or pulsing pedal, or engagement that feels grabby. If the noise happens with the pedal released, it’s more likely gearbox or input shaft bearings rather than the release bearing.

How much does thrust bearing replacement cost in Australia or New Zealand?
The bearing itself isn’t pricey, but because the gearbox has to come out, most owners fit a full clutch kit. As a rough local guide: parts $400–$900 for a quality kit, plus 5–8 hours labour. Drive-away totals commonly land around $1,200–$2,400 AUD/NZD depending on spec, brand, and workshop rates.
