Parts for your 2021 Honda Civic-Thrust bearing

2021 Honda Civic thrust-bearing: what it does and when to service it

Based on Honda’s 2016–2021 Civic Service Information and parts catalogues, the 2021 Honda Civic is fitted with thrust-bearing components. The engine uses a crankshaft thrust-bearing surface integrated into the centre main bearing set to control end float, and manual-transmission variants carry a clutch release bearing (often called a thrust bearing in workshop slang). CVT and automatic units also contain internal thrust bearings and washers, though these aren’t routine service items.

On this Civic, the engine’s thrust-bearing keeps the crankshaft from shuffling forwards and backwards under axial loads — think clutch pedal action on manuals, drivebelt loads, or transient torque. By holding the crank in the right spot, it protects the crank webs, bearings, and the oil film that everything rides on. In manual models, the clutch release bearing lets the pressure plate disengage smoothly without the pedal force grinding the rotating clutch — it’s a little rolling mediator between your left foot and the spinning clutch assembly.

There isn’t a scheduled replacement for the engine thrust-bearing, it’s inspected and measured for end play during bottom-end work using workshop specs from the Honda manual. Good oil quality and changes on time are its best mates — fresh oil maintains the protective film that thrust faces rely on. For CVT or auto cars, stick to Honda’s fluid schedule and the correct spec, internal thrust elements live happily when the fluid is clean and at the right level.

For manual Civics, the release (thrust) bearing is typically replaced whenever the clutch is out. It’s smart practice to fit it with the clutch kit while the gearbox is already on the floor, as the extra part cost is small compared with the labour to pull the transmission twice. Go with quality OEM or equivalent, verify fork and pivot condition, and lightly grease the input shaft splines and release fork contact points with the correct high-temp grease — never overdo it.

• Common signs something’s off:
  • Whirring or chirping when the clutch pedal is pressed (release bearing)
  • A clutch pedal that changes bite point or feels notchy (release bearing/fork issues)
  • Metallic scrape or a moving idle when depressing the clutch, or measurable crank end float beyond spec (engine thrust-bearing)

If a release bearing is noisy, plan a clutch-out job and replace associated wear items. If engine thrust play is out of spec, that’s an engine-bottom-end repair — best handled by a workshop that follows Honda’s service procedures and measurements.

Popular questions

Does the 2021 Honda Civic actually have a thrust-bearing?
Yes. The engine uses a crankshaft thrust-bearing surface within the main bearing set, and manual models have a clutch release (thrust) bearing. CVT/auto units also contain internal thrust elements, though they’re not serviced separately during routine maintenance.

When should the clutch release (thrust) bearing be replaced on a 2021 Civic?
Replace it whenever the clutch assembly is out, or if there’s a distinct whirring or chirp with the pedal pressed. It’s economical to install a quality release bearing along with the clutch kit to avoid a second gearbox removal later.

What maintains the engine thrust-bearing’s health on a Civic?
Timely engine oil changes with the correct spec and level. The thrust faces rely on a clean oil film. If there are signs of crank end float or clutch-pedal-induced noises that hint at axial movement, a technician should measure end play against Honda specs.
