Parts for your 2004 Honda Fit-Thrust bearing

2004 Honda Fit thrust bearing — what it does and how to look after it

Based on the Honda Jazz/Fit 2002–2008 Service Manual and Honda’s Electronic Parts Catalogue for GD1/GD3 models, the 2004 Honda Fit does use a thrust bearing. In the L-series engine (L13A/L15A), the crankshaft’s axial movement is controlled by thrust faces integrated into the main bearing set (typically at the No. 4 main journal). On manual-transmission variants, there’s also a clutch release bearing, which is a style of thrust bearing acting on the clutch diaphragm spring. CVT models don’t use a clutch release bearing, but the engine’s crank thrust bearing is still present.

That crank thrust bearing’s job is simple but crucial: it keeps the crankshaft from walking forwards and backwards when axial loads are applied — think clutch engagement on a manual, drivebelt loads, or abrupt on/off throttle events. By limiting end float, it protects the crank, bearings, oil pump gears and the gearbox input interface from misalignment and wear.

It’s not a routine “replace-by-kilometres” item, but it is a smart check during bigger jobs — sump-off service work, an engine refresh, or a clutch replacement on manuals. A technician will measure crankshaft end play with a dial indicator and compare to Honda’s spec in the service manual. If it’s out of spec, the thrust-bearing faces (part of the main bearing shells) should be renewed, and the crank’s thrust surfaces inspected for scoring.

Owners of manual Fits who do lots of stop–start driving, run a heavy-duty clutch, or tend to ride the pedal can load the thrust bearing more than usual. For those cars, it’s worth having end float checked when the clutch is out. On manuals, the clutch release bearing should always be replaced with the clutch kit, tell-tale noises include a whirr or chirp that changes when the pedal is pressed.

• Common symptoms to watch for:
  • Engine note changes when the clutch is pressed
  • Metallic scrape or knock near the crank pulley
  • Clutch engagement inconsistencies or poor idle quality on pedal application
• Service tips technicians follow:
  • Measure end float, renew thrust/main shells if out of spec
  • Inspect crank thrust faces, polish or grind only within service limits
  • Use quality bearings sized to the crank grade, torque caps to spec and recheck end float
  • On manuals, set up clutch hydraulics correctly and avoid constant pedal preload

FAQs

Does a 2004 Honda Fit actually have a thrust bearing?
Yes. The L-series engine uses thrust faces on the main bearings to control crankshaft end float. If it’s a manual, it also has a clutch release (thrust) bearing. CVT models don’t have a clutch release bearing but still rely on the engine’s crank thrust bearing.

When should the thrust bearing be replaced?
There’s no fixed interval. It’s typically replaced if crank end float is out of spec, during an engine rebuild, or when there are symptoms like end-float noise under clutch load. On manuals, the clutch release bearing is replaced whenever the clutch is renewed.

What causes thrust bearing wear on this model?
Heavy clutch loads (performance pressure plates), riding the clutch, oil starvation, and misalignment between engine and transmission can all accelerate wear. High-kilometre city driving with frequent clutch use can also contribute over time.
