Parts for your 2021 Honda Cr-v-Thrust bearing

2021 Honda CR‑V thrust bearing — what it is and how it fits into servicing

Based on Honda technical literature, a thrust bearing is indeed used on the 2021 Honda CR‑V. The L15B-series 1.5‑litre turbo engine specifies crankshaft end float control via the thrust faces on the No. 3 main bearing (Honda CR‑V 2017–2022 Service Manual: Crankshaft End Play/Main Bearing Selection). The CR‑V’s CVT (and e:HEV powertrain where fitted) also contains internal thrust/needle thrust bearings, but these are non-serviceable components documented only in transmission overhaul procedures. There is no clutch release (thrust) bearing on this model because the 2021 CR‑V was sold with a CVT/e‑CVT only (no manual gearbox in AU/NZ specifications).

Put simply, the thrust bearing in the 2021 CR‑V’s engine keeps the crankshaft from walking forwards or backwards under axial loads, like those caused by the torque converter or accessory drive loads. By controlling crank end play, it helps maintain consistent oil clearances, stable timing, and smooth gearbox engagement feel at idle. It’s not a part most owners will ever see, but it’s doing quiet, constant work every kilometre under the bonnet.

For everyday servicing, the thrust bearing isn’t a routine replacement item. It’s inspected or replaced only if there’s evidence of wear during an engine rebuild, or if end float is out of spec when measured with a dial indicator per the Honda procedure. Likewise, the CVT’s internal thrust bearings are only touched during a full transmission overhaul. The best “maintenance” for these components is really about fluid care: correct engine oil, regular changes, and the right CVT fluid, all to Honda specifications.

• What owners might notice if something’s wrong:
  • Excessive crankshaft end movement felt at the crank pulley, or a dull knock when shifting from Park to Drive at idle.
  • Metallic glitter in engine oil or unusual wear debris on the magnetic sump plug.
  • For CVT, persistent whining/judder after fluid neglect (though this isn’t specific to a single thrust bearing).
• Good care tips:
  • Use the specified low‑viscosity engine oil and change on time, oil film integrity protects the thrust faces.
  • Service the CVT with the correct Honda CVT fluid at the recommended interval, avoid overloading/towing beyond ratings.
  • If end float is suspected, have a technician measure it against the Service Manual spec before any parts are ordered.

If a thrust bearing ever needs attention on a 2021 CR‑V, it’s a workshop job with engine or transmission disassembly and precise measurement/selection of bearing thicknesses. Most well‑maintained vehicles will never need it replaced.

• Does a 2021 Honda CR‑V have a thrust bearing?
  Yes. The engine uses a crankshaft thrust bearing integrated into the main bearing set to control end float. The CVT also uses internal thrust/needle thrust bearings. There’s no clutch release thrust bearing because the 2021 CR‑V wasn’t offered with a manual gearbox in AU/NZ.
• When would a thrust bearing need replacing on a 2021 CR‑V?
  Only during an engine or transmission overhaul if end play is out of spec or there’s confirmed wear. Typical servicing doesn’t include thrust bearing replacement, diagnosis involves measuring crankshaft end float with a dial indicator and checking for abnormal wear debris.
• Can regular servicing prevent thrust bearing issues?
  It certainly helps. Using the correct engine oil and changing it on schedule, plus servicing the CVT with the specified Honda fluid, protects the bearing surfaces and reduces the chance of premature wear.
