Parts for your 2019 Isuzu D-max-Thrust bearing

2019 Isuzu D‑MAX thrust-bearing — what it is, where it’s used, and when to replace it

Technical sources confirm a thrust-bearing is relevant to the 2019 Isuzu D‑MAX, depending on context. The Isuzu D‑MAX Workshop Manual (TFR/TFS, 2012–2020, Clutch section) specifies a clutch release bearing — commonly called a thrust-bearing — on manual transmission models. Automatic models use a torque converter and do not have a clutch thrust-bearing. Separately, the Isuzu 4JJ1 Engine Workshop Manual (Engine Mechanical) specifies crankshaft thrust bearings integrated into the main bearings, these are internal engine components and not routine service items.

For D‑MAX manuals, the thrust-bearing (release bearing) sits on the gearbox input shaft and presses against the pressure plate via the clutch fork and slave cylinder. Its job is to transfer the pedal effort smoothly and take the axial load when the clutch is disengaged, keeping shifts clean and pedal feel consistent. It’s a sealed, pre‑lubed unit and isn’t greased or adjusted during normal servicing.

Owners typically don’t replace the thrust-bearing on a time or kilometre schedule, it’s done on condition or whenever the clutch is out. Most workshops will fit it as part of a complete clutch kit because the gearbox is already removed. That’s standard practice called out in OEM procedures and parts catalogues for the D‑MAX generation.

• Common symptoms of a tired thrust-bearing:
  • Whirring, chirping, or grinding noise when the clutch pedal is pressed (and quiet when released)
  • Notchy pedal feel or vibration through the pedal
  • Difficulty selecting gears with the engine running

• Service and replacement tips:
  • Replace the release (thrust) bearing whenever the clutch disc/pressure plate is replaced.
  • Inspect the clutch fork, pivot ball, guide tube, and input shaft splines for wear, replace or lightly dress as needed.
  • Do not lubricate the bearing face, it’s sealed. Only a light high‑temp grease on the guide tube and fork contact points if specified by the manual.
  • Bleed the hydraulic system and check pedal free play and engagement point after reassembly.
  • Avoid riding the clutch, heat and constant preload shorten bearing life.

How long do they last? It varies with driving style and load, but many D‑MAXs see well over 150,000 km before any clutch work. If it squeals only with the pedal down, the thrust-bearing is a suspect, if the noise is constant or changes with road speed, it may be another gearbox bearing.

Note: Automatic 2019 D‑MAX models don’t have a clutch thrust-bearing, the “thrust” function in those drivetrains is handled within the torque converter and transmission. All engines still have internal crankshaft thrust bearings, but those are addressed only during engine overhaul work.

Popular questions

Does my 2019 D‑MAX have a thrust-bearing?

Manual models do — it’s the clutch release (thrust) bearing. Automatic models don’t use one because they run a torque converter. Regardless of transmission, the 4JJ1 engine has internal crankshaft thrust bearings, but they’re not a routine service item.

What are the signs the thrust-bearing is failing on a D‑MAX?

Noise when the clutch pedal is pressed (whirr, chirp, or grind) is the classic sign. You might feel a rough or pulsing pedal. If the noise disappears when you release the pedal, the release bearing is likely. Constant noise even with the pedal up points more to other gearbox bearings.

Should the thrust-bearing be replaced with the clutch, and what’s the typical time?

Yes — replace it any time the clutch is changed. Labour for a 4x2 is commonly around 4–6 hours, a 4x4 can be 6–9 hours depending on equipment and workshop. Costs vary with parts choice (OEM vs aftermarket clutch kits) and regional labour rates in Australia and New Zealand.
