Parts for your 2007 Honda Accord-Thrust bearing

2007 Honda Accord thrust bearing — what it is, why it matters, and when to replace it

Yes, the 2007 Honda Accord is built with an engine thrust bearing. On both the 2.4‑litre K‑series four and the 3.0‑litre J‑series V6, the thrust function is integrated into the crankshaft’s main bearing set (typically the No. 3 main), controlling crank end‑float. This is documented in the Honda Accord 2003–2007 Service Manual (Engine: Crankshaft/Main Bearings/Thrust Clearance) and reflected in Honda’s OEM parts catalogues, which list a “main bearing (thrust)” for these engines. That means “thrust bearing” is relevant to this model, it’s part of the bottom end, not a routine external service item. Note: this is different to the clutch release (throw‑out) bearing on manual models.

On a 2007 Accord, the thrust bearing’s job is to keep the crankshaft centred front‑to‑back in the block, limiting axial movement when the clutch is pressed (manuals) or when the torque converter and accessory loads push on the crank (automatics). Keeping end‑float in spec preserves oil film integrity, timing alignment and smooth gearbox engagement. When healthy, it’s invisible, when worn, it can allow the crank to “walk”, leading to hard shifting, odd idle changes with the clutch pedal, or scraping/knock noises that come and go with pedal input.

It isn’t a scheduled service item and normally lasts the life of the engine. Good servicing that helps it live a long time includes fresh, quality engine oil at the recommended intervals, avoiding clutch abuse (don’t ride the pedal), and sorting any misalignment or accessory belt issues that add avoidable axial load.

Replacement is an engine‑bottom‑end job. The sump and bearing caps come off, end‑float is measured with a dial indicator, and bearing clearances are checked (often with Plastigauge). On K‑series and J‑series engines, colour‑coded main/thrust shells are selected to match block and crank identification marks, as outlined in the Honda Service Manual. New shells are installed with assembly lube, caps are torqued and angle‑tightened to spec, and end‑float is re‑checked against the factory limit. It’s smart to pair the job with a rear main seal and, if applicable, a clutch/release bearing refresh while the driveline is apart.

• Common signs to investigate: metallic rub when pressing the clutch, crank pulley moving fore‑aft, idle change when the clutch is depressed, or unexplained glitter in the oil.
• If any of these show up, a specialist should measure crank end‑float before further driving.

Popular questions about 2007 Honda Accord thrust bearings

Does a 2007 Honda Accord actually have a thrust bearing?
Yes. Both the 2.4 K‑series and 3.0 J‑series engines use a thrust function within the main bearing set to control crankshaft end‑float. It’s an internal engine component, separate from the clutch release bearing on manual cars.

What symptoms point to a worn thrust bearing on a 2007 Accord?
Look for an idle that changes when the clutch pedal is pressed, a light scrape or knock that appears with clutch input, hard shifting, or visible fore‑aft movement of the crank pulley. Any of these warrant an end‑float check with a dial indicator.

Is the thrust bearing replaced during a clutch job?
Not typically. A clutch job replaces the clutch kit and release bearing, the thrust bearing sits inside the engine’s bottom end. It’s only replaced if end‑float is out of spec or during a rebuild, though it’s wise to assess end‑float while the driveline is out.
